Perimeter of rectangles

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 10 cm and a width of 5 cm, what is its perimeter?

Back

The perimeter is 30 cm (P = 2(10 + 5) = 30).

Front

What is the unit of measurement for perimeter?

Back

The unit of measurement for perimeter can be centimeters (cm), meters (m), inches (in), or any other unit of length.

Front

What does 'perimeter' mean?

Back

Perimeter refers to the total distance around a two-dimensional shape.

Front

If a rectangle has a perimeter of 40 cm and a length of 15 cm, what is the width?

Back

The width is 5 cm (P = 2(length + width) => 40 = 2(15 + width) => width = 5).

Front

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

Back

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

Front

If you know the perimeter of a rectangle, can you find the area?

Back

Not directly; you need both the length and width to calculate the area.

Front

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

Back

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

Front

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

Back

The perimeter is 36 in (P = 2(12 + 6) = 36).
