## What is the formula for finding the perimeter of a trapezoid?

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.

## How do you find the missing side of a trapezoid?

Solve for H.

To do this, multiply each side by H, then divide each side by the angle sine. Or, you can simply divide the height of the triangle by the angle sine. So, the length of the hypotenuse, and the first missing side of the trapezoid, is about 10.4566 cm.
