To find the area under two or more than two curves, the first crucial step is to find the INTERSECTION POINTS of the curves.

Between Curve A and Line C

Between Curve A and Line B

Required Area can be calculated by breaking the problem into two parts.

I. Calculate Area under the curve A and Line B.

II. Subtract the area enclosed by curve A and Line C from the above area.

I. = Area under B and A

II. = Area under C and A

The required area under the curve
