Question

the lenght of a rectangular hall is 4 meter more than twice the breadth . if the breadth is b meter and peremeter is 19 meter . what is its length?

Answer 1

Answer:

Let breadth be b

length =(4+2b)

Now perimeter =2(l+b)

But given perimeter =19m

a/q

2(4+2b+b)=19

2(4+3b)=19

8+6b=19

6b=19-8

6b=11

b=11/6

So,l=4+2*11/6

=4+11/3
