Recall the formula for finding the area of a rectangle. define a
variable for the width and set up an equation to find the dimensions of a
rectangle that has an area 144 square inches, given that the length is 10
inches longer than its width.

Step-by-step explanation:

Given : The length is 10 inches longer than its width.

            Area of rectangle is 144 sq.inches

To Find : Define a  variable for the width and set up an equation to find the dimensions of a  rectangle

Solution:

Let the width be x

Since we are given that The length is 10 inches longer than its width.

So, Length of rectangle = x+10

Area of rectangle =

                             =  

We are given that Area of rectangle is 144 sq.inches

So,    

Since width cannot be negative

So, width of rectangle is 8 inches

Length of rectangle = x+10 = 8+10 = 18

Hence an equation to find the dimensions of a  rectangle that has an area 144 square inches is  

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
