let two sides are x&x+10
P = 140 cm
2(x+x+10)=140
2x+10=70
x=30 cm
and
other side will be x+10=40cm
P = 140 cm
2(x+x+10)=140
2x+10=70
x=30 cm
and
other side will be x+10=40cm

let the 1st side of parallelogram = x
let other side = x+10
perimeter or parallelogram = 2(a+b)
140cm =2(x+x+10)
70cm = 2x+10
70-10 = 2x
60=2x
x= 30
1st side =30 cm
other side = 30+10 =40cm
let other side = x+10
perimeter or parallelogram = 2(a+b)
140cm =2(x+x+10)
70cm = 2x+10
70-10 = 2x
60=2x
x= 30
1st side =30 cm
other side = 30+10 =40cm
