Question

Two adjacent sides of parallelogram are 3 cm and 4 cm find the perimeter of parallelogram

Answer 1

Since opposite sides in a parallelogram are equal and parallel,

let the two adjacent sides be length and breadth of a parallelogram

now length = 3 cm
and breadth = 4 cm

now perimeter = sum of all the 4 sides
= 2 × 3 + 2 × 4
= 14 cm

Answer 2

Answer:

Hence, value of perimeter of parallelogram will be 14 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 - 3 cm and 4 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,

$Perimeter = 2 (3+4) = 2 \times 7 = 14\:cm$
