Math Open Reference . Divide each of those measurements by 30. For simpler equations, use the truncated version π = 3.14, For a circle with a radius of 4cm: C = 2 x 3.14 x 4 = 25.12cm, On a square where x = 3cm, then P = 4 x 3 = 12cm, The equation P = 2(l + h) will also give you the same result: 2(8 + 5) = 2(13) = 26cm, For a quadrilateral with no equal sides, like an irregular trapezoid, use the equation P = a + b + c + d. For a quadrilateral with four equal sides, use the same equation as a square: P = 4x. If you are measuring the perimeter of a square then all you need to do is measure one side, the multiply that measurement by four.
