Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is the total distance around the rectangle, calculated by adding the lengths of all four sides.

Front

How do you calculate the perimeter of a rectangle?

Back

To calculate the perimeter of a rectangle, use the formula: P = 2(length + width).

Front

If a rectangle has a length of 5 units and a width of 3 units, what is its perimeter?

Back

The perimeter is 16 units (P = 2(5 + 3) = 16).

Front

What is the unit of measurement for perimeter?

Back

The unit of measurement for perimeter can be units, centimeters (cm), inches (in), or any other linear measurement.

Front

Back

Perimeter refers to the distance around a shape.

Front

If a rectangle has a length of 10 cm and a width of 2 cm, what is the perimeter?

Back

The perimeter is 24 cm (P = 2(10 + 2) = 24).

Front

What is the perimeter of a square with each side measuring 4 units?

Back

The perimeter is 16 units (P = 4 sides x 4 units = 16 units).

Front

If the perimeter of a rectangle is 30 units and the length is 10 units, what is the width?

Back

The width is 5 units (P = 2(length + width) => 30 = 2(10 + width) => width = 5).

Front

What is the perimeter of a rectangle with a length of 8 inches and a width of 3 inches?

Back

The perimeter is 22 inches (P = 2(8 + 3) = 22).

Front

If a rectangle has a perimeter of 40 cm and a width of 10 cm, what is the length?

Back

The length is 10 cm (P = 2(length + width) => 40 = 2(length + 10) => length = 10).
