Answer:
W=11, L=33
Step-by-step explanation: The following formula for the perimeter relates all of the given information:
P=2L+2W
So we substitute in the given information and solve for W to find
88=2(3W)+2W
88=6W+2W
88=8W
Then divide each side by 8.
11=W
The width is 11 meters. The length is then
L=3W
=3(11)
=33
or 33 meters.
