Perimeter = 2 x length + 2 x width
P = 2L + 2W
The length is 2 more than twice the width.
L = 2 x w +2 = 2w + 2
Substitution:
64 = 2(2w+2) + 2w
64 = 4w + 4 + 2w
64 = 6w + 4
60 = 6w
w = 10
The width is 10. The length is L = 2w+2 = 2(10)+2 = 20 + 2 = 22
CHECK: The perimeter is 2x10 + 2 x22 = 20 + 44 = 64.
The width is 10, the length is 22, checked, verified, and proven to be correct.
