What is the value of x so the rectangles have the same area.

a. 12 & X

b. X-2 & 16

The area of a rectangle is L x W. We have to get the value of x first so that we can find the area of the rectangle.

To get the value of x

given:

a. 12 & X

b. X-2 & 16

solution:

12x (x) = (8-2) 16

12x = 16x-32

32 = 16x - - 12x

32 = 4x

4 4

8 = x

Checking:

a. 12 & X b. X-2 & 16

Area of a rectangle = L x W Area of a rectangle = L x W

=12 x 8 = (8-2) 16

Area of a rectangle = 96 = 6 (16)

Area of a rectangle = 96
