Question

the perimeter of a parallelogram is 150 cm. and one of its side is greater than the other by 25 cm. find the length of all the sides of that parallelogram....plz answer it it's very urgent plz...

Answer 1

Let one of the sides of the paralellogram be a and the one adjacent to it be b.
The perimeter of the parallelogram=2(a+b)=150
                                                     a+b=75⇒1
Since a is greater than b by 25cm , a=b+25
By substituting it in equation 1
b+25+b=75
2b=50
b=25

a+b=75
a=75=25
a=50


Therefore the sides of the parallelogram are 50cm, 25cm,50cm,25cm,

Hope it helped you!!! :)

Answer 2

Let smaller side =x cm, then
Larger side= x+25 cm

Hence perimeter ,
=2*(smaller side + larger side)
=2*(x+x+25)= 2*(2x+25)
=4x + 50 = 150 (given)
So 4x=100
Or x =25

Smaller side = 25 cm and
Larger side = 25+25
                   = 50 cm
