Question

the perimeter of a parallelogram is 150 cm one of its side is greater than the other by 25 cm. Find the length of all the sides of the parallelogram.​

Answer 1

Solution :-

First of all we need to know that what is parallelogram ?

» Parallelogram is a quadrilateral in which opposite sides are parallel to each other .

Let us see some Properties of Parallelogram :-

▪️ Opposite sides are congruent to each other i.e they have same length.

▪️ Opposite angles are congruent to each other .

▪️ Diagonals bisect each other .

▪️ Each of the Diagonals divide the parallelogram into two congruent triangle.

Now solving the problem :-

Given :

Perimeter = 150 cm

One side is greater than other by 25 cm

Now let the smaller side be x cm

Then other side = (x + 25) cm

Now from the property of the parallelogram :-

Opposite sides are equal

→ Two of the sides = 2x

→ Two of the sides = 2(x + 25)

Now by solving it further

→ 2x + 2(x + 25) = 150

→ 2x + 2x + 50 = 150

→ 4x = 150 - 50

→ 4x = 100

→ x = 25 cm

and other side = x + 25

= 50 cm

$\sf \bold{ \therefore \: length \: of \: all \: sides \: of \: parrallelogram \: are : } \\ \\ {\sf \boxed {\underline{50cm \: , \: 25cm \: , \: 50 cm \: \: and \: 25cm}}}$
