   How do you find the perimeter of a shape?

   • Determine the length of each side. Since perimeter is just a measure of the outline of a two-dimensional figure, you don't usually need a specific formula to find perimeter (though there are equations for specific shapes to make it easier). However, you do need to know the length of all the sides of the shape.

   How do you find the perimeter of a circle?

   • Find the perimeter of a circle. Some regular shapes have formulas that make it faster for you to find the figure's perimeter. But there are other shapes, like circles, that require a formula to find perimeter. The perimeter of a circle is called the circumference. To find the circumference of a circle, use the equation C (circumference) = 2πr.

   How do you find the perimeter of a polygon?

   • Even with an irregular polygon that has 20 sides, you can still find the perimeter as long as you know the length of each side. Add the length of all the sides together. To find the perimeter of non-circular objects, find the sum of all the side lengths to determine the distance around the shape. Deal with variables.

   Mar 5, 2024 · The right way to find perimeter depends on the shape you're working with. For rectangles, use the formula p = 2 (w + h), where w is the width of the rectangle and h is the height. To find the perimeter of a square, use the formula p = 4x, where x is the length of 1 side of the square.
