Module 4: Area & Perimeter

Front

What is the formula to calculate the area of a rectangle?

Back

Area = Length x Width

Front

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

Back

15 square feet (5 x 3 = 15)

Front

What is the perimeter of a rectangle?

Back

Perimeter = 2(Length + Width)

Front

If a rectangle has a length of 10 cm and a width of 4 cm, what is its perimeter?

Back

28 cm (2(10 + 4) = 28)

Front

What is the area of a wall that is 4 feet wide and 4 feet tall?

Back

16 square feet (4 x 4 = 16)

Front

Faye cut a piece of fabric that is 3 cm wide and has an area of 24 cm. How long is the piece?

Back

8 cm (Area = Length x Width, 24 = Length x 3, Length = 8)

Front

Do two figures with the same perimeter always have the same area?

Back

No, two figures can have the same perimeter but different areas.

Front

What is the area of a rectangle with a length of 9 yards and a width of 7 yards?

Back

63 square yards (9 x 7 = 63)

Front

If the area of a rectangle is 63 square feet and the width is 7 feet, what is the length?

Back

9 feet (63 = Length x 7, Length = 9)

Front

What is the relationship between area and perimeter?

Back

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