Question

11.In a rectangle of perimeter 60 cm, one side is 10 cm longer than the other. What are lengths of the sides?​

Answer 1

Answer:

given:perimeter of rectangle=1m

=100cm

And one side is 5cm long than the other.

Let the other side be: X

Then first side will be =x+5

As we know,

perimeter of rectangle= 2(l+b)

100cm=2(x+x+5)

100cm=2(2x+5)

100cm=4x+10

4x=100-10

4x=90

therefore x=90/4

=22.5cm

first side =22.5cm. ans.

second side=22.5+5

ANS - 27.5cm.
