Calculate Parallelogram Perimeter: Finding Total Length with 6.5 and 4.5 Unit Sides

Given the parallelogram:

Calculate the perimeter of the parallelogram.

To determine the perimeter of the parallelogram, follow these steps:

• Step 1: Note the given side lengths of the parallelogram. Side $AB = 6.5$ and side $AD = 4.5$.
• Step 2: Apply the perimeter formula for a parallelogram: $P = 2(a + b)$, where $a$ and $b$ are the lengths of two adjacent sides.
• Step 3: Substitute the given lengths into the formula:

$P = 2 \times (6.5 + 4.5)$

Step 4: Perform the addition inside the parentheses: $6.5 + 4.5 = 11$

Step 5: Multiply the sum by 2 to find the perimeter: $P = 2 \times 11 = 22$

Therefore, the solution to the problem is that the perimeter of the parallelogram is $P = 22$.

Upon reviewing the choices, the correct answer is choice 4: 22.
