# The perimeter of a rectangle is 158. The length is 7 more than the width. What is the length and the width?

Width is 36, length is 43

#### Explanation:

Let the width be $x$ so the length would be $x + 7$.
The perimeter is the distance around the shape so

$x + \left(x + 7\right) + x + \left(x + 7\right) = 158$

$4 x + 14 = 158$

$4 x = 144$

$x = 36$
