Question

find the perimeter of a parallelogram if two of its adjacent sides are 12 cm and 7 cm​

Answer 1

Step-by-step explanation:

In perimeter, opposite side are equal

so All sides are = 12cm, 12cm, 7cm & 7cm = 38 cm

please mark me as brainliest

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 value of perimeter of the parallelogram.

As per question,

Parallel sides of parallelogram are - 12 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,

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