Question 2: Calculate the perimeter of a square having a side of 16 cm. This article has been viewed 50,935 times. perimeter L . 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. By using this service, some information may be shared with YouTube. A calculator that will find the area of a polygon given the coordinates of its vertices. How do I find the perimeter of an irregular shape, not regular? For quadrilaterals where the lengthwise sides are the same and the widthwise sides are the same (like a rectangle), use the equations P = 2a + 2b or P = 2(a + b). If you wanted to know how long the fence would need to be, you would need to know the perimeter. If you are trying to measure the perimeter and don’t have access to this calculator just remember that perimeter is the length of all the sides of a shape or the distance around the shape.
