area and perimeter

Front

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

Back

Perimeter = 2 × (Length + Width)

Front

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

Back

Perimeter = 2 × (10 + 5) = 30 meters

Front

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

Back

Area = Length × Width

Front

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

Back

Area = 8 × 4 = 32 cm²

Front

What is the perimeter of a rectangle with a length of 12 feet and a width of 3 feet?

Back

Perimeter = 2 × (12 + 3) = 30 feet

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 does 'area' mean in geometry?

Back

Area is the amount of space inside a shape, measured in square units.

Front

If the area of a rectangle is 24 square feet and the width is 4 feet, what is the length?

Back

Length = Area / Width = 24 / 4 = 6 feet

Front

What is the relationship between perimeter and area?

Back

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

Front

If a rectangle has a perimeter of 50 cm and one side is 15 cm, what is the other side?

Back

Other side = (Perimeter/2) - one side = (50/2) - 15 = 10 cm
