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

Back

The perimeter of a square is calculated as P = 4 × side length. Therefore, P = 4 × 5 cm = 20 cm.

Front

If a triangle has sides measuring 3 cm, 4 cm, and 5 cm, what is its perimeter?

Back

Front

What is the perimeter of a rectangle with a length of 10 ft and a width of 4 ft?

Back

Using the formula P = 2(length + width), the perimeter is P = 2(10 ft + 4 ft) = 28 ft.

Front

What is the relationship between the sides of a rectangle and its perimeter?

Back

The perimeter of a rectangle is directly related to the lengths of its sides; increasing the length or width increases the perimeter.

Front

If a fence encloses a rectangular yard with a length of 15 m and a width of 10 m, what is the perimeter?

Back

The perimeter is calculated as P = 2(length + width) = 2(15 m + 10 m) = 50 m.
