The length of a rectangle is 8 more than the width. The area is 660 square yards. Find the length and width of the rectangle.

A (area) = L (length) x W (width).

L = W + 8, therefore A = (W + 8) x W

660 = W2 + 8W

W2 + 8W - 660 = 0

Factor to get (W + 30) x (W - 22) = 0

Possible solutions are W = -30 and W = 22.

W can't be < 0 so the only solution for W = 22 yd.

L = W + 8 = 30 yd.

22 x 30 = 660 yd2

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
