Question

find the perimeter of a parallelogram pqrs in which pq =5cm and qr =7cm option 22 24 26 27​

Answer 1

Answer:

22

Step-by-step explanation:

perimeter=2* sum of adjacent sides

$= 2 \times (5 + 7) \\ = 2 \times 11 \\ = 22$

Answer 2

The perimeter of the given parallelogram is 24 cm.

Given,

Two adjacent sides of a parallelogram pqrs, pq = 5 cm, qr = 7 cm.

To find,

The perimeter of the parallelogram pqrs.

Solution,

The perimeter is defined as the length or distance around a two-dimensional shape or figure.

Let there be a parallelogram having sides $a$ and $b$, then, its perimeter is given by,

$P=2(a+b)$     ...(1)

Here, the sides of the given parallelogram pqrs are,

$a =pq=5 cm,\\b=qr=7cm.$

So, the perimeter of parallelogram pqrs, using (1), will be,

$P=2(5+7)=2 \times 12$

⇒ P = 24 cm.

Therefore, the perimeter of the given parallelogram is 24 cm.
