Question

find the sides of a parallelogram if one of its sides is longer than the other by 15 cm and its perimeter is 250 CM​

Answer 1

Answer:

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.

Answer 2

Answer:

perimeter=250cm

if one Side is 15cm then opposite side of it will also be 15cm

15+15+x+x=250

30+2x=250

2x=250-30

2x=220

x=220÷2

x=110
