Question

perimeter of parallelograme is 150cm. one of its side os greater than the other side by 25cm. fimd the lengths of all sides.

Answer 1

opposite sides of parallelogram are congruent

then the lengths of the sides of parallelogram are
x,x+25,x,x+25 cm

perimeter of parallelogram=sum of all sides
150=x+x+x+25+x+25
150=4x+50
150-50=4x
100=4x
100/4=x
x=25


then the sides of parallelogram are 25cm, 25cm and x+25=25+25=50cm and 50cm

ANS
THE LENGTHS OF SIDES OF PARALLELOGRAM ARE
I)25cm
II)50 cm
III)25cm
IV)50 cm
