Answer 1

Answer:

b'length of the rectangular field=9Km

breadth of the rectangular field=4.5Km

area of field,A=length*breadth

=9*4.5

=40.5Km

2

length of the lake=(9-6)Km

=3Km

breadth of the lake=(4.5-2)Km

=2.5Km

Area of lake,a=3*2.5

=7.5Km

2

Pr=

A

a

=

40.5

7.5

=0.18

Thus the probability that it crashed inside the lake is 0.18
