Question

Gabriella needs 120120 meters of fence to surround a rectangular garden.The length of the garden is three times its width, w.How wide is the fence?

Answer 1

Take into account that if Gabriella needs 120 meters, then, the perimeter of the rectangular figure must be equal to 120 m.

Based on the given expressions for the sides of the rectangular figure, you can write:

w + w + 3w + 3w = 120

8w = 120

w = 120/8

w = 15

Hence, the fence has a width of 15 meters.
