Question

Two sides of a parallelogram are such that one of the sides is 10 cm longer than the other side.if perimeter of the parallelogram is 140 cm,find the length of each of its sides?

Answer 1

Hey there!!

The length of one side be ' x '

The other side = ' x + 10 '

Perimeter = sum of all sides

Parallelogram = 4 sides

x + x + x + 10 + x + 10 = 140

4x + 20 = 140

4x = 120

x = 30

sides = 30 , 40 , 30 , 40

Answer 2

Hey Mate!
________

Parallelogram = $\bold{4\: sides}$

Let the length of one side be $\bold{x}$

The other side = > $\bold{x + 10}$

Perimeter = sum of all sides

$\bold{= > x + x + x + 10 + x + 10 = 140}$

$\bold{= > x + x + x + x \: = 4x}$

$\bold{= > 10 + 10 = 20}$

$\bold{= > 4x + 20 = 140}$

$\bold{= > 4x = 120}$

Thus, $\large{\bold{\fbox{x = 30}}}$

Sides are :— $\bold{30, 40, 30, 40}$
