Trapezoid Perimeter Calculator

Formula

The formula to calculate the perimeter of a trapezoid is:

$P = a + b + c + d$

Where:

$P$ is the perimeter of the trapezoid
$a$ is the length of the first parallel side
$b$ is the length of the second parallel side
$c$ is the length of the first non-parallel side
$d$ is the length of the second non-parallel side

What is the Perimeter of a Trapezoid?

The perimeter of a trapezoid is the sum of the lengths of all its four sides. A trapezoid is a four-sided polygon with one pair of parallel sides known as the bases and two non-parallel sides known as the legs. To calculate the perimeter of a trapezoid, you simply add the lengths of these four sides together. This is true regardless of whether the trapezoid is right-angled, isosceles, or scalene. The formula for the perimeter of a trapezoid is $P = a + b + c + d$ , where $a$ and $b$ are the lengths of the bases, and $c$ and $d$ are the lengths of the legs.

Example Calculation

Let's assume the following values:

Length of the First Parallel Side (a): 5 units
Length of the Second Parallel Side (b): 7 units
Length of the First Non-Parallel Side (c): 4 units
Length of the Second Non-Parallel Side (d): 6 units

Step 1: Calculate the Perimeter:

$P = 5 + 7 + 4 + 6 = 22 \text{ units}$

Therefore, the perimeter of the trapezoid is 22 units.
