Zack measured a rectangular garden at the park. The longer sides each measured 15 feet and were 3 times longer than the shorter sides. If Zack walked all the way around the garden, how far did he walk?

Given:

The longer sides of a rectangular garden = 15 feet

It were 3 times longer than the shorter sides.

To find:

The total distance covered by Zack if he walked all the way around the garden.

Solution:

Let the shorter side be x.

Longer side = 15 feet

According to given equation, longer side is 3 times longer than the shorter sides.

Divide both sides by 3.

So, the measure of shorter side is 5 feet.

The total distance covered by Zack if he walked all the way around the garden is the perimeter of the garden.

Perimeter of rectangular garden is

Therefore, the total distance covered by Zack is 40 feet.
