Calculate Parallelogram Perimeter: Given Sides 15 and 10 Units

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

• Step 1: Identify the given side lengths
• Step 2: Use the perimeter formula for a parallelogram
• Step 3: Perform the calculation to find the perimeter

Now, let's work through each step:
Step 1: The problem tells us that the lengths of two adjacent sides of the parallelogram are 15 and 10.
Step 2: We'll use the formula for the perimeter of a parallelogram, which is $P = 2(a + b)$, where $a$ and $b$ are the two sides.
Step 3: Plugging in the values, we have $P = 2(15 + 10) = 2 \times 25 = 50$.

Therefore, the perimeter of the parallelogram is $50$.
