The perimeter of a parallelogram is 140 cm. If one of the sides is longer than the other by 10 cm. Find the length of each of its sides.​

Answer 1

$\Large {\textsf{\textbf \red{Answér :-}}}$

• Perimeter of a parallelogram :

2x + 2(x + 10) = 140

2x + 2x + 20 = 140

4x = 120

x = 30 cm.

• Substitute x in equation (1), we get;

x = 40 cm.

• Sides are 30cm and 40cm.

Answer 2

Answer:

perimeter of parallelogram=140cm

let one side be x

other side be 10x

perimeter of parallelogram=2(a+b)

140 =2(x+10x)

140 =2x+20x

140 =22x

140/22 =x

70/11 =x

sides are 70/11

and 700/11

is your answer

hope it helps you
