The length of the rectangular garden is 12 m and the width is 1/3 of the length. How long is the fence needed around the garden?
The solution of the problem:
In order to answer the question of the problem, we need to find the perimeter of the garden, and since the garden is rectangular, the perimeter of the garden will be equal to the perimeter of the rectangle, that is, the sum of all four sides. First you need to find out the width of the garden.
1. What is the width of the garden?
12 * 1/3 = 4 meters.
2. Find out how long the fence around the garden is needed, that is, what is the perimeter of the garden.
12 + 12 + 4 + 4 = 32 meters.
Answer: Around the garden you need a fence thirty-two meters long.
