Front

What is the formula for calculating the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is calculated using the formula P = 2(length + width).

Front

How do you calculate the area of a rectangle?

Back

The area (A) of a rectangle is calculated using the formula A = length × width.

Front

What is the difference between perimeter and area?

Back

Back

Perimeter is measured in linear units, such as centimeters (cm) or meters (m).

Front

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

Back

The perimeter is P = 2(10 cm + 5 cm) = 30 cm.

Front

If a rectangle has a length of 8 m and a width of 4 m, what is its area?

Back

The area is A = 8 m × 4 m = 32 sq m.

Front

What is the perimeter of a square with a side length of 6 cm?

Back

The perimeter of a square is P = 4 × side length, so P = 4 × 6 cm = 24 cm.
