Blake's Area and Perimeter Practice

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 the perimeter of a square with each side measuring 5 cm?

Back

The perimeter is 20 cm (P = 4 × side length).

Front

If a rectangle has a length of 8 cm and a width of 3 cm, what is its area?

Back

The area is 24 square cm (Area = 8 cm × 3 cm).

Front

What is the formula for finding the area of a triangle?

Back

Area = 1/2 × base × height.

Front

If a triangle has a base of 6 cm and a height of 4 cm, what is its area?

Back

The area is 12 square cm (Area = 1/2 × 6 cm × 4 cm).

Front

What is the perimeter of a shape with sides measuring 3 cm, 4 cm, and 5 cm?

Back

The perimeter is 12 cm (3 cm + 4 cm + 5 cm).

Front

How do you find the missing side of a shape if you know the perimeter?

Back

Subtract the sum of the known sides from the total perimeter.
