Question

the perimeter of the parallelogram is 170 cm one of its sides is 5 cm more than the other find the side of the parallelogram​

Answer 1

Answer:

40 and 45 is the answer.

Step-by-step explanation:

Let 1st side of parallelogram is X cm.

2nd side is (x+5) cm

perimeter =2( l+b ) = 170cm

=> 2( x+x+5 )=170 cm

=> 2( 2x+5 ) =170cm

=> 4x+5 = 170 cm

=> 4x = 170- 5

=> 4x = 160 cm

=> X = 160/4

=> X = 40

1st side = 40cm

2nd side = 40+5 = 45
