Calculate Parallelogram Perimeter: Given Sides 11 and 7 Units

To solve this problem, we'll follow these steps:

• Step 1: Identify the given side lengths of the parallelogram.
• Step 2: Apply the formula for the perimeter of a parallelogram.
• Step 3: Calculate the perimeter using the identified side lengths.

Now, let's work through each step:
Step 1: The problem states that the lengths of sides AB and BC in the parallelogram are 11 and 7 units, respectively.
Step 2: The formula for the perimeter $P$ of a parallelogram is $P = 2 \times (\text{side 1} + \text{side 2})$.
Step 3: Substituting the given lengths into the formula, we have:
$P = 2 \times (11 + 7) = 2 \times 18 = 36$.

Therefore, the perimeter of the parallelogram is $\mathbf{36}$ units.
