Answer:I'll explain below, just follow the directions. I can't directly draw it. Step-by-step explanation:find the length and the width of a rectangle whose perimeter is 18 ft 2L + 2W = 18 simplify, divide by 2 L + W = 9 L = (9-W) : whose area is 20 square feet L*W = 20 Replace L with (9-W)  W(9-W) = 20 -W^2 + 9W - 20 = 0 Multiply by -1, easier to factor W^2 - 9W + 20 Factors to (W-4)(W-5) = 0 Two solutions W = 4 ft is width, then 5 ft is the Length and W = 5 ft is the width, then 4 ft
