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

If a rectangle has a length of 10 meters and a width of 5 meters, what is its perimeter?

Back

P = 2(10 + 5) = 30 meters.

Front

What is the definition of area?

Back

Area is the amount of space inside a shape.

Front

How do you calculate the area of a rectangle?

Back

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

Front

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

Back

A = 8 × 3 = 24 square meters.

Front

What is the relationship between perimeter and area?

Back

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

Front

If the perimeter of a rectangle is 40 meters and the width is 10 meters, what is the length?

Back

Length = (Perimeter/2) - Width = (40/2) - 10 = 10 meters.

Front

What is the formula for the perimeter of a square?

Back

P = 4 × side length.

Front

If one side of a square is 6 cm, what is its perimeter?

Back

P = 4 × 6 = 24 cm.
