Question

Two adjacent sides of a parallelogram are 12cm, 7cm. Find the perimeter of the parallelogram.

Answer 1

Answer:

38

Step-by-step explanation:

$2 \times (12 + 7) \\ = 2 \times 19 \\ = 38$

Answer 2

Answer:

Hence, value of perimeter of parallelogram will be 38 cm

Step-by-step explanation:

In context to question asked,

We have to determine the perimeter of parallelogram.

As per question,

Adjacent sides of parallelogram = 12 cm and 7 cm

As we know that,

• Parallelogram is the quadrilateral whose opposite sides are equal and parallel.

• None of angle of parallelogram is of right angle.

The perimeter of parallelogram can be determined by using formula -

$Perimeter = 2 \times (a+b)$, where a and b are adjacent sides of parallelogram.

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

Thus we will get,

$Perimeter = 2(12+7) = 2\times 19 = 38\:cm$
