To describe: how could estimate the area of the playground.
Answer to Problem 25HP
Explanation of Solution
Given information: Suppose a playground is in the shape of a composite figure that has
a curved side that is not a semicircle.
Calculation:
A composite figure is made up of two or more shapes. To find the area of a composite figure, decompose the figure into shapes with areas, know how to find. Then find the sum of those areas.
Sometimes it is necessary to break a problem into parts, can use colored pencils to shape each separate figure that makes up the composite figure a different color. Find the area of each part, and then combine the solution of the parts.
One way to estimate the area of a composite figure is to draw a rectangle around the figure. The area of the figure should be slightly less than the area of the rectangle.
