Answer 1

Answer:

Given the ratio of breadth and length of a hall = 2:5

also given, breadth of the hall = 10 and length of the hall = 25

then, the ratio of breadth and length \frac{10}{25}=2:5

25

10

=2:5

to find the missing figures

we multiply 25\times2=5025×2=50

we multiply 20\times2=2020×2=20 is the first missing figure.

hence the second breadth of hall=20 and length of the hall=50

for finding second missing figure, we have

40=10\times440=10×4

so to find the second missing figure we multiply 25\times4=10025×4=100

hence, third breadth of the hall= 40 & length=100.
