Calculate the perimeter of triangles, squares, rectangles, trapezoids, polygons, and circles. Inputs and results are in any available length unit. For results, select the row and choose an alternative unit type.

- Side: Length of the side of the square

-Length: Length of the rectangle

-Width: Width of the rectangle

- Base: Length of the triangle's base

- Side 1: Length of one side of the triangle

- Side 2: Length of the other side of the triangle

- Base: Length of the trapezoid's base

- Side 1: Length of one side of the trapezoid

- Top: Length of the trapezoid's top

- Side 2: Length of the other side of the trapezoid

- Sides: Number of sides to this polygon

- Length: Length of one side of the polygon

- Diameter: Diameter of the circle

The room is 10' by 15'. How many linear feet of trim are needed?

In the Rectangle section:

- Length: 10ft

- Width: 15ft

This room required 50ft of trim. If the result is not in feet, select the Rectangle's Perimeter row and choose ft.
