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.
