Question

In a parallelogram two adjacent sides have measures 5cm and 7cm respectively. Find its perimeter.​

Answer 1

___________________________

★ Gɪᴠᴇɴ :-

• Adjacent sides are = 7cm , 5 cm
• Length → largest side = 7 cm
• Breadth → Smallest side = 5cm

★ Sᴏʟᴜᴛɪᴏɴ :-

As we know that

Perimeter of parallelogram = 2( l + b )

Here ,

• l → length = 7cm
• b → breadth = 5cm

Substituting the values we have ,

➙ 2( 7 + 5 )

➙ 2( 12 )

➙ 24 cm

Answer 2

Answer:

Hence, value of perimeter of parallelogram will be 24 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 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,

$Perimeter = 2 (5+7) = 2 \times 12 = 24\:cm$
