Front

What is the perimeter of a rectangle with a length of 10 cm and a width of 5 cm?

Back

30 cm (Perimeter = 2(10 + 5) = 30).

Front

If a square has a side length of 4 inches, what is its perimeter?

Back

16 inches (Perimeter = 4 sides x 4 inches = 16).

Front

What is the perimeter of a triangle with sides measuring 3 cm, 4 cm, and 5 cm?

Back

12 cm (Perimeter = 3 + 4 + 5 = 12).

Front

What is the perimeter of a rectangle with a length of 12 feet and a width of 6 feet?

Back

36 feet (Perimeter = 2(12 + 6) = 36).

Front

What is the perimeter of a shape with sides measuring 2 cm, 3 cm, and 5 cm?

Back

10 cm (Perimeter = 2 + 3 + 5 = 10).

Front

If the perimeter of a rectangle is 20 cm and the length is 6 cm, what is the width?

Back

4 cm (Perimeter = 2(length + width) => 20 = 2(6 + width) => width = 4).

Front

What is the perimeter of a square with a side length of 5 meters?

Back

20 meters (Perimeter = 4 sides x 5 meters = 20).

Front

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

Back

10 cm (Perimeter = 2(length + width) => 50 = 2(15 + width) => width = 10).
