Question

The length of a rectangular garden is 3 times the width, . The perimeter of the garden is 100 feet. Which of the following equations can be used to find the width of the garden, in feet?


6w = 100

8w = 100

3w = 100

4w = 100

Answer 1

ANSWER

6w = 100

EXPLANATION

The formula for calculating the perimeter of a rectangular building is P=2l +2w.

From the question, the perimeter of the garden is 100 feet.

It was given that, the length of a rectangular garden is 3 times the width.

This implies that,

$l = 3w$

We substitute into the formula to get:

$2(3w)+2w = 100$

$6w+2w = 100$

This simplifies to:

$8w = 100$
