1. Find the perimeter and area of the following rectangles whose dimensions are:

(i) length = 11 cm, breadth = 5 cm

(ii) length = 6.7 cm, breadth = 5.1 cm

(iii) length = 14 m, breadth = 6 m

(iv) length = 8 feet, breadth = 3 feet

Solution:

(i)

Given that,

length = 11 cm, breadth = 5 cm

Rectangle Area = length x breadth

= 11 x 5 = 55 cm²

Rectangle Perimeter = 2(length + breadth)

= 2(11 + 5) = 16 x 2 cm

= 32 cm

ˆ´ The Rectangle area is 55 cm², perimeter is 32 cm.

(ii)

Given that,

length = 6.7 cm, breadth = 5.1 cm

Rectangle Area = length x breadth

= 6.7 x 5.1 = 34.17 cm²

Rectangle Perimeter = 2(length + breadth)

= 2(6.7 + 5.1) = 2 x 11.8 cm

= 23.6

ˆ´ The Rectangle area is 34.17 cm², perimeter is 23.6 cm.

(iii)

Given that,

length = 14 m, breadth = 6 m

Rectangle Area = length x breadth

= 14 x 6 = 84 m²

Rectangle Perimeter = 2(length + breadth)

= 2(14 + 6) = 20 x 2 = 40 m

ˆ´ The Rectangle area is 84 m², perimeter is 40 m.

(iv)

Given that,

length = 8 feet, breadth = 3 feet

Rectangle Area = length x breadth

= 8 x 3 = 24 sq feet

Rectangle Perimeter = 2(length + breadth)

= 2(8 + 3) = 11 x 2 = 22 feet

ˆ´ The Rectangle area is 24 sq feet, perimeter is 22 feet.

2. The area of a rectangle is 92 m², its length is 8 m. Find the rectangle breadth and perimeter?

Solution:

Given that,

Rectangle area = 92 m²

Rectangle length = 8 m

The rectangle area formula is

So, breadth = area / length

= 11.5 m

Rectangle Perimeter = 2(Length + breadth)

= 2(8 + 11.5) = 2(19.5) = 39 m

ˆ´ The Rectangle breadth is 11.5 m, perimeter is 39 m.

3. If the rectangle perimeter is 28 cm, its width is 18 cm. Find the rectangle length and area?

Solution:

Given that,

Rectangle Perimeter p = 28 cm

Width w = 18 cm

Rectangle perimeter p = 2(l + w)

28 = 2l + 36

2l = 28 – 36

2l = 8

l = 8/2

l = 4 cm

Rectangle area A = (l x w)

= 18 x 4 = 72 cm²

ˆ´ The Rectangle length is 4 cm, area is 72 cm².

4. Find the cost of tiling a rectangular plot of land 250 m long and 500 m wide at the rate of $8 per hundred square m? Solution: Given that, The rectangular plot length = 250 m Rectangular plot width = 500 m Area of rectangular polt = length x width = 250 x 500 = 125000 sq. m Cost of tiling =$8 per 100 sq. m = $8/100 per 1 sq. m Cost of tiling of rectangular polt of 125000 sq. m = (8/100) x 125000 = 10,000 ˆ´ The cost of tiling of the rectangular plot is Rs. 10,000/-. 5. A room is 4 feet long and 6 feet wide. How many square feet of carpet is needed to cover the floor of the room? Solution: Given that, Rectangle length l = 4 feet Rectangle width w = 6 feet Area of the rectangle A = l x w A = 4 x 6 A = 24 sq feet So, 24 sq feet of carpet is needed to cover the room floor. 6. A table-top measures 5 m by 3 m 50 cm. What is the area and perimeter of the table? Solution: Given that, Table length l = 5 m width w = 3 m 50 cm = 3 + 50 x (1/100) = 3 + 1/2 = 7/2 = 3.5 m Table Perimeter p = 2(l + w) = 2(5 + 3.5) = 2(8.5) m = 17 m Table area A = l x w A = 5 x 3.5 = 17.5 m² ˆ´ The table area is 17.5 m², the perimeter is 8.5 m. 7. A floor is 25 m long and 14 m wide. A square carpet of sides 8 m is laid on the floor. Find the area of the floor that is not carpeted and floor perimeter? Solution: Given that, Rectangular floor-length l = 25 m Rectangular floor breadth b = 14 m Square carpet side s = 8 m Rectangular floor area A = l x b A = 25 x 14 A = 350 m² Area of the square carpet a = s x s a = 8 x 8 a = 64 m² Area of the floor that is not carpeted = Rectangular floor area – Area of the square carpet = A – a = 350 – 64 = 286 m² Rectangular flooe perimeter P = 2(l + b) P = 2(25 + 14) P = 2(39) = 78 m ˆ´ Area of the floor that is not carpeted is 286 m², rectangular floor perimeter is 39 m. 8. How many tiles whose length and breadth are 15 cm and 6 cm respectively are needed to cover a rectangular region whose length and breadth are 510 cm and 135 cm? Solution: Given that, Length of the tile l = 15 cm Breadth of the tile b = 6 cm Rectangular region length = 510 Rectangular region breadth = 135 Area of the tiles = l x b = 15 x 6 = 90 cm² Area of the plot = 510 x 135 = 68,850 cm² Number of tiles required = Area of plot / Area of tiles = 68850 / 90 = 765 Therefore, the required number of tiles are 765. 9. How many rectangles can be drawn with 22 cm as a perimeter? Also, find the dimensions of the rectangle whose area will be maximum? Solution: Given that, The perimeter of the rectangle = 22 cm 2(l + w) = 22 (l + w) = 22/2 = 11 Possible dimensions of the rectangle are (1, 10), (2, 9), (3, 8), (4, 7), (5, 6), (6, 5), (7, 4), (10, 1), (9, 2), (8, 3), (7, 4). ˆ´ The dimensions of the rectangle whose area is maximum is (6, 5) or (5, 6) and 11 rectangles can be drawn. 10. The perimeter of a rectangular pool is 140 m, and its length is 60 m. Find the pool width and area? Solution: The rectangular pool perimeter p = 140 m Rectangular pool length l = 60 m Rectangular pool width w = ? Rectangular pool perimeter p = 2(l + w) 140 = 2(60 + w) 140 = 120 + 2w 2w = 140 – 120 2w = 20 w = 20/2 w = 10 Rectangular pool area A = l x w A = 60 x 10 A = 600 ˆ´ The rectangular pool width is 10 m, area is 600 m². 11. The length of a rectangular wooden board is four times its width. If the width of the board is 155 cm, find the cost of framing it at the rate of$5 for 20 cm?

Solution:

Given that,

Width of a rectangular wooden board w = 155 cm

The cost of framing = $5 for 20 cm The length of a rectangular wooden board l = 4w l = 4 x 155 l = 620 Wooden board perimeter P = 2(l + w) P = 2(620 + 155) = 2(775) = 1550 The cost of framing =$5/20 for 1 cm

The cost of wooden board framing = 1550 x (5/20)

= 7750/20

= 387.5

ˆ´ The cost of framing is \$387.5.
