Question

the perimeter of a parllelogram ABCD is 140cm if One of the sides is greater than the other by 10cm.find the length of all sides of the parllelogram

Answer 1

Let breath be x so length be x+10.
perimeter of parallelogram= 2(l+b)
140cm=2(x+x+10)
140cm=2(2x+10
140cm=4x+20
4x=140-20
4x=120cm
x=30cm.
so breath =30cm and length =30+10=40cm

Answer 2

Let the one side =x

Other side=x+10

Perimeter of parallelogram=2(l+b)

140=2(x+x+10)

140/2=2x+10

70=2x+10

70-10=2x

60=2x

60/2=x

30=x

one side =30cm

second side 30+10=40cm
