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
