The length of a rectangle is 4 centimeters less than its width. What are the dimensions of the rectangle if its area is 117 square​ centimeters?
Answered by oobleck
usually the length is greater than the width, but if we take the larger dimension to be x, then we have
x(x-4) = 117

Hint: 117 = 9*13

L = W - 4

W(W - 4) = 117 ... W^2 - 4 W - 117 = 0

factor to find W
