A rectangular us four times as long as it is wide. if the area is 144 ft^2, find the length and width of the table

x (4x) = 144 {area is width x length}

4x^2 = 144 {multiplied x by 4x}

x^2 = 36 {divided both sides by 4}

x = 6 {took square root of both sides}

4x = 24 {substituted 6, in for x, into 4x}

width = 6ft and length = 24ft
