Answer:
width = 10 yards
Explanation:
the perimeter (P ) of a rectangle is calculated as
P 2( length + width )
let width be w then length = 2w
given P = 60 , then substitute into the formula for P
60 = 2(2w + w)
60 = 2(3w) , that is
60 = 6w ( divide both sides by 6 )
10 = w and l = 2w = 2 × 10 = 20
width = 10 yards and length = 20 yards
