Question

The permiter of a parallelogram is 147 centimeter is one of the side is longer than the other by 10 cm Find the length of each of its side ?

Answer 1

let one side be x
therefore other side will be x+10
opposite sides of parallelogram are equal
therefore=
x+x+10+x+x+10=147
4x+20=147
4x=127
x=127/4
x=31.75
one side=31.75
other side=41.75
