Question

two adjacent sides of a parallelogram have length 5 cm and 4 cm find the perimeter of parallelogram​

Answer 1

Answer: 18 cm.

Step-by-step explanation:

opposite sides of a parallelogram are equal

so the 4 sides of the parallelogram = 4 cm,4 cm,5 cm,5 cm

so therefore,

Perimeter = (5+5+4+4) cm

                  = 18 cm(ans)

hope it helps you!

Answer 2

Answer:

Hence, value of perimeter of parallelogram will be 18 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 - 5 cm and 9 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,

$Perimeter = 2 (5+4) = 2 \times 9 = 18\:cm$
