It is good to recall that 1yd = 3ft. To solve this problem, you take the number of yards given to you (in this case 4.5 yd) and you can multiply it by 3ft. Another way to think of it is this way:

Hi Destinee- So you are trying to find out how many feet are in 4.5 yards. First, remember that there are 12 inches in a foot and that three feet make up a yard. So with that in mind, you take 1yrd.=3ft. and you mutiply it by 4.5. (4.5)(3ft.)=13.5ft.
