Calculate Parallelogram Perimeter: Finding the Total Length of a 5.6 × 2.8 Shape

Question

Calculate the perimeter of the following parallelogram:

00:07 Let's calculate the perimeter of the parallelogram.

00:10 Remember, in a parallelogram, opposite sides have the same length.

00:21 The perimeter is found by adding up the lengths of all four sides.

00:47 And that's how you find the perimeter! Great job!

To solve this problem, we apply the perimeter formula for parallelograms:

Step 1: Identify the lengths of sides $a$ and $b$ . The problem gives us $a = 5.6$ and $b = 2.8$ .
Step 2: Substitute these values into the formula $P = 2(a + b)$ .
Step 3: Calculate the result:
$a + b = 5.6 + 2.8 = 8.4$ .
$P = 2 \times 8.4 = 16.8$ .

Therefore, the perimeter of the parallelogram is $16.8$ .
