Question

A plane MH370 is reported to have crashed somewhere in the rectangular region shown in fig. The probability that it crashed inside the lake (shown in the figure) is

\frac{P}{110}

. Find the value of 'P'. Type the answer in the blank below:

___

Answer:
:
Solution: Area of the entire region where the helicopter can crash = (5.5

\times

10)km

^{2}

=55 km

^{2}

Area of the lake = (3

\times

3.5) km

^{2}

=10.5 km

^{2}

Probability that helicopter crashed inside the lake=

\frac{10.5}{55} = \frac{21}{110}

.
So, P = 21
