A rectangle has a perimeter of 84 meters and a length of 35 meters. What is the width of the rectangle?

1 answer

Let's start by using the formula for the perimeter of a rectangle:

P = 2L + 2W

where P is the perimeter, L is the length, and W is the width.

We know that the perimeter is 84 meters and the length is 35 meters. Plugging those values into the formula, we get:

84 = 2(35) + 2W

Simplifying:

84 = 70 + 2W
14 = 2W
7 = W

Therefore, the width of the rectangle is 7 meters.
