Perimeter, Area, & Volume

Front

What is Perimeter?

Back

The perimeter is the total distance around the outside of a shape. It is calculated by adding the lengths of all the sides.

Front

How do you calculate the area of a rectangle?

Back

Area = Length × Width. For example, if a rectangle has a length of 5 cm and a width of 3 cm, the area is 15 cm².

Front

What is Volume?

Back

Volume is the amount of space inside a three-dimensional object. It is measured in cubic units.

Front

How do you calculate the volume of a rectangular prism?

Back

Volume = Length × Width × Height. For example, if a prism has a length of 4 cm, width of 3 cm, and height of 2 cm, the volume is 24 cm³.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × Base × Height. For example, if the base is 6 cm and the height is 4 cm, the area is 12 cm².

Front

What units are used to measure area?

Back

Area is measured in square units, such as cm², m², or ft².

Front

What is the difference between area and perimeter?

Back

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

Front

How do you find the area of a square?

Back

Area = Side × Side. If a square has a side length of 5 cm, the area is 25 cm².

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (Length + Width). For example, if a rectangle has a length of 5 cm and a width of 3 cm, the perimeter is 16 cm.

How do you calculate the area of a circle?

Back

Area = π × Radius². If the radius is 3 cm, the area is approximately 28.27 cm².
