Perimeter / Area Composite Figures

Front

What is Perimeter?

Back

Perimeter is the total distance around the outside of a shape.

Front

How do you calculate the Perimeter of a Rectangle?

Back

Add the lengths of all four sides or use the formula: P = 2(length + width).

Front

What is Area?

Back

Area is the amount of space inside a shape, measured in square units.

Front

How do you calculate the Area of a Rectangle?

Back

Multiply the length by the width: Area = length × width.

Front

What is a Composite Figure?

Back

A composite figure is a shape made up of two or more simple shapes.

Front

How do you find the Area of a Composite Figure?

Back

Calculate the area of each simple shape and then add them together.

Front

What is the formula for the Area of a Square?

Back

Area = side × side or Area = side².

Front

If the area of a square is 36 square feet, what is the length of one side?

Back

6 feet (since 6 × 6 = 36).

Front

What is the relationship between Perimeter and Area?

Back

Perimeter measures the boundary length, while Area measures the space inside.

Front

How do you find the Length of a Rectangle if you know the Perimeter and Width?

Back

Use the formula: Length = (Perimeter/2) - Width.
