If the area of the region ( x , y ) : 0 ≤ y ≤ min 2 x , 6 x - x 2 is A , then 12 A is equal to _______.

If the area of the region (x,y):0ymin2x,6x-x2 is A, then 12 A is equal to _______.

Solution

Solving, y=2x and y=6x-x2

2x=6x-x2

4x-x2=0

x4-x=0

x=0,4

y=0,8

x,y0,0, 4,8

So, the required area is given by,

A=12×4×8+466x-x2dx

A=16+3x2-x3346

A=763

12A=304
