Question

A helicopter crashed in a dense forest area which is in the shape of a rectangle of dimension
9km by 4.5km .There is a water body inside the forest in the shape of a square of side 2.5km.
Find the probability that the helicopter has fallen into the water body.​

Answer 1

Answer:25/162

Step-by-step explanation:

Area of forest = 9km*4.5km

Area of the water body = 2.5*2.5km2

Probability=2.5*2.5/9*4.5=25/162

Answer 2

$=.1543$

Step-by-step explanation:

dimension of rectangle forest

                 $9km\times 4.5km$

dimension of water body inside forest

$2.5km\times 2.5km$

area of rectangle plane$=9\times 4.5$

$=40.5km^{2}$

area of water region$=2.5^{2}$

$=6.25km^{2}$

probability of helicopter fallen in water=area of water region/area of rectangle region

$=6.25/40.5$

$=.1543$
