Question

the perimrter of a parallelogram is 120 cm. if one side is greater than the other by 9 cm, find the length of all the sides of the parallelogram.​

Answer 1

Answer:

it's help full uuu.......

Answer 2

Perimeter: 120 cm

let one side be

$x$

let the adjacent side be

$x + 9$

we know that,

"opposite sides of parallelogram are equal"

therefore, there will be 2 sides with length

$x$

and 2 sides with length

$x + 9$

therefore, we get this equation:

$x + x + x + 9 + x + 9 = 120$

(because perimeter is 120)

$x + x + x + 9 + x + 9 = 120 \\ 4x + 18 = 120 \\ 4x = 120 - 18 \\ 4x = 102 \\ x = 102 \div 4 \\ x = 24$

as x=24,

we can now find the lengths of the sides of the parallelogram.

the sides are:

x=24

x=24

x+9=24+9=33

x+9=24+9=33

therefore the sides are: 24cm, 24cm, 33cm, 33cm

hope it helped!!
