Study Notes

Area of a Compound Shape

There is no specific formula for finding the area of a compound shape, as it depends on the shapes that make up the compound shape.
To find the area, split the compound shape into individual shapes, find the area of each, and then add them up.

Perimeter of a Compound Shape

A common mistake when finding the perimeter of a compound shape consisting of a rectangle and a triangle is to forget to include the diagonal side that borders the two shapes.

Preparing to Find the Area

Before finding the area of a compound shape, break it down into individual shapes, such as rectangles, triangles, or circles, to make it easier to calculate the area.
