area and perimeter

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

If a rectangle has an area of 36 and the width is 4, what is the length?

Back

Length = Area ÷ Width = 36 ÷ 4 = 9

Front

If the perimeter of a rectangle is 20 feet and the width is 8 feet, what is the length?

Back

Length = (Perimeter ÷ 2) - Width = (20 ÷ 2) - 8 = 2 feet

Front

What is the relationship between area and perimeter in a rectangle?

Back

Area measures the space inside the rectangle, while perimeter measures the distance around it.

Front

If the perimeter of a rectangle is 34 meters and the width is 4 meters, what is the length?

Back

Length = (Perimeter ÷ 2) - Width = (34 ÷ 2) - 4 = 13 meters

Front

The area of a rectangle is 72 sq units. One side length is 9 units. What is the other side length?

Back

Other side length = Area ÷ One side length = 72 ÷ 9 = 8 units

Front

If the perimeter of a rectangle is 42 and the length is 6, what is the width?

Back

Width = (Perimeter ÷ 2) - Length = (42 ÷ 2) - 6 = 15 units

Front

What does it mean if a rectangle has a larger area than perimeter?

Back

It means the rectangle is more 'spread out' and has a larger space inside compared to the distance around it.

Front

What is the unit of measurement for area?

Back

Square units (e.g., square feet, square meters)
