Question

the length of a rectangle is 12 centimeters less than its width . what are the dimensions of the rectangle if it’s area is 108 square centimeters?

Answer 1

Length = 6 and Width = 18 = 6(18) = 108

Explanation:

Length = W-12

Areas of a rectangle = L(W)

= W-12(W) = 108

W^2-12w = 108

W^2-12w-108=0

Solve for W

(W-18) (W+6)

W = 18, -6

L = 18-12 = 6
