Question

One of the sides of parallelogram is 10cm more than the other. If the perimeter of the parallelogram is 120cm, then the shortest side is __________

a) 45
b) 15
c) 25
d) 35
​

Answer 1

Answer:

c)25 cm

Step-by-step explanation:

Let one of the side be Xcm(let it be AB of //ABCD)

As we know 2 opposites side of a parallelogram are equal ...

Hence...CD=Xcm

From the statement given=> BC=DA=(X+10)cm

Perimeter=AB+BC+CD+DA=4X+20=120

Thus, we get X=25cm

Thank you☺️

Answer 2

Answer:

option c =25

Step-by-step explanation:

a parallelogram has

4 sides

in which opposite sides are equal

so

let "x" be the shortest part of figure

according to data another side is x+10

perimeter of parallelogram is

2(l+b)

so

2(x+x+10)=120

2x+10=60

2x=50

x=25

the shortest part =25
