Question

if the length of a rectangle is 9 cm and perimeter is 18 ring breadth.

Answer

Breadth of the rectangle = 9cm

Let us take the length be x.

Let us take the length be= X

Then it's perimeter

=2(l+b)=2(x+9)cm.=2x+18cm.

But it is given 30cm.

So ,Atq . 2x +18=30cm

or2x =30-18cm

or2x = 12cm

so x=6cm.
