Areas of Composite Figures and Circles A

The area of a composite figure is the total space inside the figure, which can be found by adding the areas of its individual shapes.

The amount of space inside a shape.

A = l•w, where l is the length and w is the width.

A = 1/2 • b • h, where b is the base and h is the height.

A = πr², where r is the radius of the circle.

The distance around the circle, calculated as C = 2πr or C = πd, where d is the diameter.

A = 1/2 • (b1 + b2) • h, where b1 and b2 are the lengths of the two bases and h is the height.

A composite figure is a shape made up of two or more simple shapes, such as rectangles, triangles, and circles.

Find the area of each individual shape and then add them together.

Area measures the space inside a shape, while perimeter measures the distance around a shape.
