# How to get the perimeter of a trapezoid?

#### Understand the Problem

The question is asking for the method to calculate the perimeter of a trapezoid, which involves summing the lengths of all its sides.

The perimeter of a trapezoid is calculated by adding the lengths of all its sides.

The perimeter of a trapezoid is calculated by adding the lengths of all its sides.

#### Steps to Solve

1. Identify the lengths of all four sides of the trapezoid

Ensure you have the lengths of the two parallel sides (bases) and the two non-parallel sides (legs).

Let the lengths of the sides be denoted as $a$, $b$, $c$, and $d$, where $a$ and $c$ are the lengths of the parallel sides and $b$ and $d$ are the legs.

1. Use the perimeter formula for a trapezoid

The perimeter $P$ of a trapezoid is the sum of all its sides.

$$P = a + b + c + d$$

Sum the values of $a$, $b$, $c$, and $d$ to find the perimeter.

For example, if $a = 5$ units, $b = 3$ units, $c = 7$ units, and $d = 4$ units:

$$P = 5 + 3 + 7 + 4 = 19 \text{ units}$$

The perimeter of a trapezoid is calculated by adding the lengths of all its sides.
