Question

A parallelogram has side lengths 7 inches and 11 inches. Find the perimeter.

Step-by-Step Solution

Answer

The perimeter of the parallelogram is $P=36\text{ inches}$

Step 1. Indicate the side lengths of a parallelogram with expression.

$\begin{array}{l}a=7\text{ inches}\\ b=11\text{ inches}\end{array}$

Step 2. Formula used.

$\text{Perimeter of a parallogram }P=2\left(a+b\right)$

Step 3. Calculate the perimeter of the given parallelogram.

To find the perimeter of the given parallelogram, use the above formula and substitute 7 for a and 11 for b and solve further as shown below:

$\begin{array}{l}P=2\left(7+11\right)\\ P=36\text{ inches}\end{array}$ 

Therefore, the perimeter of the given parallelogram is 36 inches.
