The perimeter of the rectangle is 72 feet.
The ratio of the width to the length is 5 to 7.
What are the dimensions of the rectangle?
:
let x = the multiplier
then
5x = the width
and
7x = the length
:
The perimeter = 72
2(7x) + 2(5x) = 72
simplify, divide by 2
7x + 5x = 36
12x = 36
x = 36/12
x =3 is the multiplier
therefore
7(3) = 21 ft is the length
and
5(3) = 15 ft is the width

Check
2(21) + 2(15) = 72
