Question

the perimeter of a parallelogram is 120 CM one of its side is greater than the other by 10 cm find the length of all the sides separately

Answer 1

Answer:25,25,35,35

Step-by-step explanation:

In parallelogram opposite sides are equal

So,let opposite sides be x and other opposite sides be x+10

So, x+x+x+10+x+10=120

4x+20=120

4x=100

x=25

x+10=35

Answer 2

let X cm be the one of it's side then another will be X+10 cm
$the \: total \: perimeter \: is \: given \: by \\ x + x +( x +10) + (x + 10) = 120 \\ 4x + 20 = 120 \\ 4x = 100 \\ x = 25cm \\ another \: side \: will \: be \: \\ x + 10 = 25 + 10 = 35cm$
