Question

The area of a rectangle is 70 in² and the length of the rectangle is 3 in. longer than the width. The area of a rectangle is found by multiplying the length times the width. During the Set Up step of the five-step problem-solving plan, which equation would you set up to solve for the width

Answer 1

well i know the length is 10 and the width is 7

Answer 2

`w(w+3)=70`

Explanation:

Let w be the width of the rectangle.

We have been given the length of the rectangle is 3 in. longer than the width. So the length of the rectangle would be
`w+3`.

We are also told that the area of a rectangle is 70 in². We know that area of rectangle in length times width. We can represent the given information in an equation as:

`w(w+3)=70`

Therefore, the equation
`w(w+3)=70` can be used to find the width of the rectangle.
