• Elementary area: The area is called elementary area which is located at any arbitary position within the region which is specified by some value of  between  and 
• The area of the region bounded by the curve y = f (x), x-axis and the lines x = a and x = b (b > a) is given by the formula: 
• The area of the region bounded by the curve , y-axis and the lines y = c, y = d is given by the formula: 
• The area of the region enclosed between two curves y = f (x), y = g (x) and the lines x = a, x = b is given by the formula, Area = , where  in [a, b].
• If  in [a, c] and  in [c, b],  then we write the areas as : Area = .
