The length of a rectangle is five times the width.

Question

The length of a rectangle is five times the width. If the area is 180 square inches, find the length and width of the rectangle.

Answer 1

Area of rectangle is L * W

180 = L *W

W= X

L= 5X

180 = X * 5X

180 = 5X^2

180/5 = X^2

36 = X^2

X = 6

So, W = 6, L = 30

It checks out because also:

180 = 6 * 30
