w= width
l= 2w= length
Perimeter of a Rectangle Formula
P= 2(l + w)
substitute 2w for l in equation
180= 2(2w + w)
multiply 2 by parentheses
180= 4w + 2w
combine like terms
180= 6w
divide both sides by 6
30 yards= w
LENGTH
2w= 2(30)= 60 yards
CHECK:
180= 30 + 60 + 30 + 60
180= 90 + 90
180= 180
ANSWER: the width is 30 yards and the length is 60 yards
Hope this helps! :)
