Question

A rectangle that has an area of 357 square inches is 17 inches wide. How long is the rectangle?

Answer 1

Hi Serenafrancis1! :)

The formula for the area of a rectangle is:

`L*W`

`L=length`

`W=Width`

We can input all the information we know to solve for the missing variable:

`L*17=357`
Divide both sides by 17

`(L*17)/17=(357)/17`
Simplify.

`L=21`

The rectangle is 21 inches long.

Hope this helps.
