5.4H Area and Perimeter

Front

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

Back

Perimeter (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 m + 5 m) = 30 m

Front

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

Back

Area (A) = Length × Width

Front

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

Back

A = 8 ft × 4 ft = 32 ft²

Front

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

Back

P = 4 × Side = 4 × 6 cm = 24 cm

Front

What is the area of a square with a side length of 5 m?

Back

A = Side × Side = 5 m × 5 m = 25 m²

Front

If a rug has a perimeter of 90 feet and each side is equal, what is the length of one side?

Back

Length of one side = Perimeter / 4 = 90 ft / 4 = 22.5 ft

Front

What is the relationship between perimeter and area?

Back

Perimeter measures the distance around a shape, while area measures the space inside the shape.

Front

How do you convert centimeters to millimeters?

Back

Multiply the number of centimeters by 10.

Front

If a rectangle has a length of 12 cm and a width of 3 cm, what is its perimeter in millimeters?

Back

P = 2 × (12 cm + 3 cm) = 30 cm = 300 mm
