# How do you find the perimeter of a trapezoid?

A:

To find the perimeter of a trapezoid, add up the length of each of the sides of the shape. Use the equation P = a + b + c + d.

1. Understand the equation

The equation to use to find the perimeter of a trapezoid is P = a + b + c + d. In this equation the P stands for perimeter, while the a, b, c and d each stand for one side of the trapezoid. In order to use this equation, you need to know the values of each side of the trapezoid.

2. Fill in the equation

To fill in the values for the equation, look at each side of the trapezoid. The two sides that are parallel to each other are the bases, and are the a and b sides. The remaining two sides of the trapezoid are the c and d sides. Take the value for each of these sides, and fill it into the equation.

3. Solve the equation

Add up the values of the equation to get the perimeter of the trapezoid. For example, if the equation is P = 4 + 6 + 2 + 3, the answer would be P = 15.
