Answer:
10 inches (each side)
Step-by-step explanation:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
perimeter = 2l + 2w = 58 in
2(18) + 2w = 58 in
36 + 2w = 58 in
2w = 58 - 36
2w = 22 in
w = 22 divided by 2
w = 11 in
2(18) + 2w = 58 in
36 + 2w = 58 in
2w = 58 - 36
2w = 22 in
w = 22 divided by 2
w = 11 in
