Question

The length of a rectangle is 6cm longer than its width.
If the perimeter of the rectangle is 36cm , find its area.

Answer 1

A = w * (w + 6) = 6 * 12 = .....

Answer 2

Let x = width of the rectangle
x+6 = length of the rectangle

Perimeter = 2(W) + 2(L) = 36
2(x) + 2(x+6) = 36
2x + 2x + 12 = 36
4x + 12 = 36



4x = 24
x= 6 cm Width
x+6 = 12 cm Length


Area = L*W = 12 cm * 6 cm = ----------sq cm.
