Area of a Composite Figure What is the area of the composite figure? Round to the nearest tenth. A 713.1 ft2 B 852.5 ft2 C 953.1 ft2 D 992 ft2 Read the Item The figure can be separated into a rectangle with dimensions 16 feet by 32 feet, a triangle with a base of 32 feet and a height of 15 feet, and two semicircles with radii of 8 feet. Lesson 4 Ex1

Area of a Composite Figure Solve the Item Area of composite figure Area formulas Substitution Simplify. Use a calculator. Answer: The area of the composite figure is 953.1 square feet to the nearest tenth. The correct answer is C. Lesson 4 Ex1

Find the Area of a Composite Figure to Solve a Problem A rectangular rose garden is centered in a border of lawn. Find the area of the lawn around the garden in square feet. The length of the entire lawn is 25 + 100 + 25 or 150 feet. The width of the entire lawn is 25 + 20 + 25 or 70 feet. The length of the rose garden is 100 feet and the width is 20 feet. Lesson 4 Ex2

Find the Area of a Composite Figure to Solve a Problem area of composite figure – area of rose garden Area formulas Substitution Simplify. Simplify. Answer: The area of the lawn around the garden is 8500 square feet. Lesson 4 Ex2

Find the area of polygon MNPQR. Coordinate Plane Find the area of polygon MNPQR. First, separate the figure into regions. Draw an auxiliary line perpendicular to from M (we will call this point S), an auxiliary line from N to the x-axis (we will call this point K), and an auxiliary line from P to the Origin, O. This divides the figure into triangle MRS, triangle NKM, trapezoid POKN and trapezoid PQSO. Lesson 4 Ex3

Now, find the area of each of the figures. Coordinate Plane Now, find the area of each of the figures. Find the difference between y-coordinates to find the lengths of the bases of the triangles and the lengths of the bases of the trapezoids. Find the difference between x-coordinates to find the heights of the triangles and trapezoids. Lesson 4 Ex3
