Answer:

Width = 14ft     Length = 20ft

Step-by-step explanation:

Area (A) of rug (having rectangular shape) = L× W          A = [tex]280ft^{2}[/tex]

but Length is 6ft more than width, this means L = (6 + W)ft

∴ 280 = (6+W)×W

    280 = 6W + [tex]W^{2}[/tex]

solving the equation as a quadratic equation;  [tex]W^{2} + 6W - 280 = 0[/tex]

(W - 14) (W + 20) = 0

W = 14 or W = -20                 but W ≠ negative

∴ Width (W) = 14ft

Length = 6 + 14

            = 20ft
