Answer: 5 length & width
Step-by-step explanation:
Since this is a square all sides would be the same length & width which would be 5 because each side is symmetric. So if you do 5 times as many sides as there is (5 x 4) it would give you 20
So the LENGTH of EACH side is 5 and the AREA in total or PREMIETER would be 20 all together.
