After going through the video, graphics and text, you are now able to identify a polygon based on its properties, find the perimeter of any polygon by adding the lengths of all the polygon's sides, and apply knowledge of regular polygons to calculate perimeter quickly, using the formula P = n × s P = n × s where n is ...

A composite figure is made up of triangles, squares, rectangles, semicircles, and other two-dimensional figures. Here are two examples. To find the perimeter of a composite figure, find the distance around the figure. The perimeter is about 20 + 12 = 32 inches.

The formula for finding the perimeter of a triangular prism, for example, would be the sum of the three lengths of the triangle that makes up the base, or: Perimeter of triangle = a + b + c where a, b and c are the three lengths of the triangle.

This would be the perimeter of a rectangular prism formula: Perimeter of rectangle: 2l + 2w where l is the length of the rectangle and w is the width. Apply standard perimeter calculations to the base shape of the prism, and that gives you the perimeter.

In these formulae r is the radius and d is the diameter. C = π X d (3.14159 x 10) = 31.42 (to 4 s. f.) To calculate the perimeter of an arc (part of a circle) from the angle you can calculate the fraction of the circle. = 4.19cm (to 3 s.f.) The perimeter of the whole sector is therefore 4.19 + 8 = 12.19 (4 s.f.).

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.

The perimeter of a circle is known as the circumference. To calculate the circumference of a circle you can use one of two formulae, either: C = 2πr or C = πd. In these formulae r is the radius and d is the diameter. C = π X d (3.14159 x 10) = 31.42 (to 4 s. f.)

Multiply the length of one side of a regular polygon by the number of sides to find its perimeter. Regular polygons have identically sized sides. For example, if the shape is a regular pentagon, which has 5 sides, with a side length of 4 inches, then multiplying 4 inches by 5 results in a perimeter of 20 inches.

To calculate the perimeter of a shape, we add the lengths of each side. To find the perimeter of this irregular triangle, we add up the three side lengths. A tip for teaching perimeter of irregular shapes is to cross off each side length as you have added it.

Set it up! Find the perimeter of the following rectangle by using the formula P=2L+2W, where L represents the legth and W represents the width of the rectangle. To find the perimeter, let L=2x+3 (the legth) and W=x+1 (the width) and plug these values into the formula P=2L+2W.

Calculating the perimeter of a rhombus or diamond is simple because of its equal-length sides. Find the length of one of the diamond's sides. For this example, the length is 45. Multiply the length by 4 to calculate the diamond's perimeter.

Step 1: Remember that perimeter is the measure of the outer edge of a shape, or otherwise, the sum of the measures of the sides of the trapezoid. Representing the perimeter by P, and the sides as a, b, c and d, our formula is P= a + b + c + d.
