Best ResponseYou've already chosen the best response.0call the length x and so the width is x7 to get the area of a rectangle it's length times width so; area = 660 = x(x7) => 0 = x^2 7x 660 Then use the quadratic formula and use the positive value :) ... this should work

Best ResponseYou've already chosen the best response.0complete the square should work as well (x7/2)^2 49/4660 = 0 (x7/2)^2 = 2689/4 (x7/2) = + 2sqrt(165) x = 7/2 + 2sqrt(165)
