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

Step-by-step explanation:

l=

4×x=4x

b=

x

perimeter of rectangle=2( l+b)

2(4x+X)

2(5x). =19

10x. =19

x=19/10

1.9m

length=1.9×4=7.6

Answer 2

Answer:

l=2b+4

b

2 (l+b)=19

2(b+2b+4)=19

2b+b=19-5/2

3b=15/2

b=15/2×3

b=5/3

l=2 (5/3)+4

10/3+ 4

10/3+12/3

10+12/3

22/3

l=22/3
