Area, Perimeter and Volume

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

Area = Length × Width.

Front

What is Perimeter?

Back

Perimeter is the total distance around a shape, measured in linear units.

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 × (Length + Width).

Front

What is Volume?

Back

Volume is the amount of space occupied by a 3D object, measured in cubic units.

Front

How do you calculate the volume of a rectangular prism?

Back

Volume = Length × Width × Height.

Front

If a rectangle has a width of 7 feet and an area of 35 square feet, what is its length?

Back

Length = Area ÷ Width = 35 ÷ 7 = 5 feet.

Front

What is the formula for finding the perimeter of a square?

Back

Perimeter = 4 × Side Length.

Front

If the perimeter of a rectangle is 28 cm, and the length is 10 cm, what is the width?

Back

Width = (Perimeter ÷ 2) - Length = (28 ÷ 2) - 10 = 4 cm.

Front

What is the volume of a cube with a side length of 3 inches?

Back

Volume = Side Length³ = 3³ = 27 in³.
