A rectangle has twice the width. if the perimeter is 66 yards find the length and the width

Length of rectangle is twice its width.

Let the width = b

length = 2b

Perimeter = 66

=> 2 (length + width) = 66

=> 2 (2b + b) = 66

=> 2 * 3b = 66

=>6b = 66

=> b = 66/6 = 11 yard

So width = 11 yards

length = 2b = 2*11 = 22 yards.
