Area of a Composite Figure
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.
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.
Find the Area of a Composite Figure to Solve a Problem
INTERIOR DESIGN Cara wants to wallpaper one wall of her family room. She has a fireplace in the center of the wall. Find the area of the wall around the fireplace.
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.
