    Length (l) is the same as width (w) and their product is 64.

    Length (l) is the same as width (w) and their product is 64. We're given 2 equations: lw = 64 l = w Substitute equation (2) into equation (1): w * w = 64 w^2 = 64 w = 8 Since l = w, then l = 8

    If the perimeter of a rectangular field is 120 feet and the length of one side is 25 feet, how wide

    If the perimeter of a rectangular field is 120 feet and the length of one side is 25 feet, how wide must the field be? The perimeter of a rectangle P, is denoted as: P = 2l + 2w We're given l = 25, and P = 120, so we have 2(25) + 2w = 120 Simplify: 2w + 50 = 120 Typing this equation into our...
