Front

What is the definition of perimeter?

Back

The 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 the definition of area?

Back

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: A = length × width.

Front

What is the definition of volume?

Back

The amount of space inside a three-dimensional object, measured in cubic units.

Front

How do you calculate the volume of a rectangular prism?

Back

Multiply the length, width, and height: V = length × width × height.

Front

If a square has a perimeter of 40 feet, what is the length of each side?

Back

10 feet (since each side is equal, divide the perimeter by 4).

Front

What is the formula for the area of a square?

Back

A = side × side or A = side².

Front

What is the relationship between area and perimeter?

Back

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

Front

What is the formula for the perimeter of a square?

Back

P = 4 × side.
