Question

The sides of a parallelogram are 11cm and 9cm. Find the perimeter of the parallelogram

Answer 1

The perimeter of parallelogram would be 40 cm.

Step-by-step explanation:

Since we have given that

Sides = 11 cm and 9 cm

Since we know that the opposite sides are equal.

so, the sides would be

11, 9, 11, 9

So, Perimeter of parallelogram would be

$2(l+b)\\\\=2(11+9)\\\\=2\times 20\\\\=40\ cm$

Hence, the perimeter of parallelogram would be 40 cm.

Answer 2

Answer:

Hence, value of perimeter of parallelogram will be 40 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 = 11 cm and 9 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,

$Perimeter = 2(11+9) = 2\times 20 = 40\:cm$
