Alessandra Cunningham · Answer 1

4 meters

Step-by-step explanation:

l is length and w is width

l=3w

2l+2w=32.

this are the two equations you can use to solve for the answer.

since l is 3w the second equation becomes 2 (3w) + 2w=32.

2 times 3w is 6w. So 6w+2w is 8w.

You are left with 8w=32 divide both by 8 and the answer is w=4.
