Answer:
6.3
Step-by-step explanation:
Two sides are 9.6 meters long. The perimeter is 31.8 meters.
31.8-9.6-9.6=12.6 the remaining two sides.
12.6/2=6.3 represents the lengths of the other twp sides.
P=2(L+W)
if length=7
and P=24
24=2(7+W)
divide both sdes by 2
12=7+W
minus 7both sides
5=W
width=5meters
