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.

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.

The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers. ... You can count that there are 16 squares, so the area is 16 square units.

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.

The perimeter of Δ ABC is 24 inches, and the perimeter of Δ DEF is 12 inches. When you compare the ratios of the perimeters of these similar triangles, you also get 2 : 1. This leads to the following theorem. Theorem 60: If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b.

This Python program allows user to enter the length and width of a rectangle. By using the length and width, this program finds the perimeter of a rectangle. TIP: The math formula to calculate perimeter of a rectangle: perimeter = 2 * (Length + Width).

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.).
