What is the formula for calculating the perimeter of a triangle?

Back

The perimeter of a triangle is calculated by adding the lengths of all three sides: P = a + b + c.

Front

How do you calculate the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated using the formula: P = 2(length + width).

Front

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

Back

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

Front

What is the perimeter of an equilateral triangle with each side measuring 12cm?

Back

The perimeter is calculated as P = 3 * side length. For a side length of 12cm, P = 3 * 12 = 36cm.

Front

How do you find the perimeter of a trapezoid?

Back

The perimeter of a trapezoid is found by adding the lengths of all four sides: P = a + b + c + d.

Front

What is the perimeter of a rectangular swimming pool with a length of 20m and a width of 7m?

Back

Using the formula P = 2(length + width), the perimeter is P = 2(20 + 7) = 54m.

Front

What is the perimeter of a rectangular picture frame with a length of 18in and a width of 4in?

Back

Using the formula P = 2(length + width), the perimeter is P = 2(18 + 4) = 44in.

Front

What is the formula for calculating the perimeter of a rhombus?

Back

The perimeter of a rhombus is calculated as P = 4 * side length.

Front

If a rhombus has a side length of 9mm, what is its perimeter?

Back

Using the formula P = 4 * side length, the perimeter is P = 4 * 9 = 36mm.
