Question

find the sides of paralleogram if one of its side is longer than the other by 15 cm and it's perimeter is 250 cm​

Answer 1

Answer:

Length of one side(l)=15 cm

Length of other side be b

2(l+b)=56

l+b=28[56/2]

15+b=28

b=8–15=13 cm

Answer 2

Answer:

The side of the parallelogram is 55cm & 70cm.

Step-by-step explanation:

Let's assume one side as $x$

Given, another side is 15cm longer than $x$

So, other side will be :

$(x + 15) \sf cm.$

Perimeter of the parallelogram is given by :

$2(l + b)$

Where,

• $l$ is $(x + 15)$
• $b$ is $x$

So, the perimeter of the parallelogram is :

$\to 2(x + 15 + x)$

$\to 2(2x + 15)$

$\to 4x + 30$

But, the perimeter of the parallelogram is 250cm. (given)

Therefore,

$\implies 4x + 30 = 250$

$\implies 4x = 250 - 30$

$\implies 4x = 220$

$\implies x = \dfrac{220}{4}$

$\implies x = 55$

$\therefore \sf One \: side \: of \: the \: parallelogram \: is \: 55cm.$

Hence,

The other side is :

→ 55 + 15 = 70cm.
