The perimeter of a rectangular concrete patio is 68 meters. The patio is 24 meters long. how wide is it?

Perimeter formula for a rectangle:

2w+2L=p, where:

w = width

L = length

a = perimeter.

We are giving the length: 24. We need to find the width.

However, don't panic, since we are also given the perimeter: 68.

Just plug in numbers and leave "w" as the only variable.

2w + 2 (24) = 68

Simplify.

2w+48=68

2w=20

w=10

The patio is 10 meters wide.

10 meters.

68-24-24/2=10
