Area and Perimeter Warm-Up

Front

What is the formula for the area of a rectangle?

Back

Area = length × width

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width)

Front

What is the unit of measurement for area?

Back

Square units (e.g., cm², ft²) are used to measure area.

Front

What is the unit of measurement for perimeter?

Back

Linear units (e.g., cm, ft) are used to measure perimeter.

Front

If a rectangle has a length of 5 cm and a width of 3 cm, what is its area?

Back

Area = 5 cm × 3 cm = 15 cm²

Front

If a rectangle has a length of 8 ft and a width of 2 ft, what is its perimeter?

Back

Perimeter = 2 × (8 ft + 2 ft) = 20 ft

Front

What is the area of a square with a side length of 4 cm?

Back

Area = side × side = 4 cm × 4 cm = 16 cm²

Front

What is the perimeter of a square with a side length of 4 cm?

Back

Perimeter = 4 × side = 4 × 4 cm = 16 cm

Front

What is the area of a circle with a radius of 3 in?

Back

Area = π × radius² ≈ 3.14 × (3 in)² ≈ 28.26 in²

Front

What is the circumference of a circle with a diameter of 10 in?

Back

Circumference = π × diameter ≈ 3.14 × 10 in ≈ 31.4 in
