Find the Area of Composite Figures
Find the area of the composite figure. Round to the nearest tenth if necessary.
First, separate the figure into a rectangle and a triangle. Then find the sum of the areas of the figure.

Solve Multi-Step Problems
CARPETING Carpeting costs $2 per square foot. How much will it cost to carpet the area shown?
Understand You know the dimensions of the figure. You need to find its area.
Plan First, separate the figure into a rectangle and two trapezoids. Then find the sum of the areas of the figure.

Solve Multi-Step Problems
Step 1 Find the area to be carpeted.
Area of Rectangle
A = bh Area of a rectangle
A = (18)(20) Replace b with 18 and h with 20.
A = 360 Simplify.
Solve
The area of the rectangle is 360 square feet.

Solve Multi-Step Problems
Area of Trapezoid
Solve
The area of both trapezoids is 70 • 2 or 140 square feet.

Solve Multi-Step Problems
Answer: So, it will cost $1,000 to carpetthe area shown.
Step 2 Find the cost of the carpeting.
2(500) = 1000
The area to be carpeted is 360 + 140 or 500 square feet.
