Question

Two adjacent side of parallelogram are 4 cm and 7 cm . find its perimeter

Answer 1

A perimeter is the sum of all the sides in a closed figure. A parallelogram has 4 sides as it is a quadrilateral.
We know that the two adjacent sides of the parallelogram are 4 and 7 cm.
∴ Perimeter = 4 + 4 + 7 + 7 = 22cm

or 2 *(4 + 7) = 22 cm [using distributive property]

Answer 2

Answer:

Hence, value of perimeter of parallelogram will be 22 cm

Step-by-step explanation:

In context to question asked,

We have to determine the value of perimeter of the parallelogram.

As per question,

Parallel sides of parallelogram are - 4 cm and 7 cm

As we know that,

• Opposite sides of parallelogram are parallel and equal.
• Perimeter of any figure can be determined by adding the length of sides of outer border of the figure.

So, for determining the value of perimeter of parallelogram we will use the formula - $Perimeter = 2 (l +b) = 2 (Sum\: of \:both \:sides)$

So, for determining the value of perimeter of parallelogram we will put the value of sides given in the question in above formula,

Thus we will get,

$Perimeter = 2 (4+7) = 2 \times 11 = 22\:cm$
