Video Solution

Solution Steps

00:00 Calculate the perimeter of the parallelogram

00:03 Opposite sides are equal in a parallelogram

00:07 Let's substitute the side value

00:13 These sides are also opposite therefore equal

00:18 Let's substitute the side value

00:29 The perimeter of the parallelogram equals the sum of its sides

00:47 Let's substitute appropriate values and solve for the perimeter

00:53 And this is the solution to the question

Step-by-Step Solution

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

Let's proceed with the solution:

Step 1: The problem provides the side lengths of the parallelogram as $AB = 20$ units and $AD = 15$ units.

Step 2: Use the formula for the perimeter of a parallelogram, $P = 2(a + b)$ , where $a = 20$ and $b = 15$ .

Step 3: Plug the side lengths into the formula:

P = 2(20 + 15) = 2 \times 35

Calculating further, we get:

P = 70

Therefore, the perimeter of the parallelogram is $70$ .
