Calculate Parallelogram Perimeter: Given Side Lengths 3 and 9

Given the parallelogram:

Calculate the perimeter of the parallelogram.

To determine the perimeter of the parallelogram, we need first to identify the lengths of the sides:

• From the problem, one side ($a$) is $9$ units, and an adjacent side ($b$) is $3$ units.

Using the formula for the perimeter of a parallelogram, $P = 2(a + b)$, we can substitute the known values:

• $a = 9$
• $b = 3$

Substituting these values into the formula gives us:

$P = 2(9 + 3)$

$P = 2 \times 12$

$P = 24$

Therefore, the perimeter of the parallelogram is $24$.
