Question

Perimeter of a rectangular is given 30cm.if breadth is given as b and length is 29cm.Find its breadth

Answer 1

Step-by-step explanation:

let the length be x.

And breadth is 6cm.【GIVEN】

Perimeter= 2(l+b)

Solution:-

= 2(x+6)=30

= 2x+12=30

=2x=(30-12)cm

= 2x= 18cm

= x= 18/2

= x= 9cm.

Now, length is 9cm.

Area:

l×b

= 9cm×6cm

= 54cm^2
