## Answer

Answer)
Let’s start with option(1) and see whether ratio of length and
breath of B to A are 2.5 each.
**The graph in which ratio of length of B to length of A
and breath of B to breath of A is 2.5 each,that option is
correct.**
By analysing visually,**we get graph in the option(4) is
the CORRECT ANSWER.** Let’s see why-:
Now Look at the graph given in option(4)-:
Length of A =3
Length of B = 7.5
Ratio of length = length of B/length of A = 7.5/3 = 2.5
Breath of A = 5
Breath of B = 2
Ratio of breath = breath of B/breath of A = 5/2 = 2.5

**As we can see ratio of both length and breath is
2.5.Therefore, Graph in option(4) is the answer.**
