I really don't understand this

So seeming as the perimeter is length multiplied by the width, then all we have to do is divide the perimeter by the length, which you have, and kaboom you have your answer.
So putting this into the equation:
20.5 = Width x 5.25
Therefore 20.5 / 5.25 = Width
Which comes to an answer of 3.9 feet.
Hope i could help :)
Yo dude the answer is 5.
if you subtract 20.5 by 5.25x2 you will get 10...next divide the 10 by 2 and you have your answer...5...
