7-86.

Complete the area model shown below, then complete parts (a) through (c) below.

What is the sum of the areas of each of the rectangles that makes up the larger one?

Multiply the sides to find the area of the six smaller rectangles.

What are the length and width of the large rectangle?

Add all the areas of the six smaller rectangles.

Remember to find a common denominator.Write a statement of the form

Area as *a**sum*for this rectangle.See parts (a) and (b) for the length, width, and area.

Add the values above the large rectangle together for the width and then add the ones to the side for the height.

Both should equal 1.
