The sides of a triangle are in the ratio of 1:2:2 and the perimeter of the triangle is 15 feet. The length of the shortest side is 2.5 feet 3 feet 5 feet 7.5 feet

The ratio is 1:2:2, but the total perimeter (length) is 15. If the triangle legs were actually 1, 2, and 2, what would the perimeter be? Once you know that, how many times do you have to multiply that to get 15?
