Step-by-step explanation:
Heya :-
Heya :-Given :-
- Length = 77m.
- breadth = 50m.
- diameter = 14m
To Find :-
- the probability of the event that it fell in the lake
Area of rectangular garden= l × b
= 77 × 50
= 3850m^2
area of circular lake = π × r^2
= 22/7×7^2
=154 cm^2
area of circular lake/ area of rectangular garden
= 154/3850
= 1/25cm ^2
Hence the the probability of the event that it fell in the lake is 1/25cm^2

Answer:
area of rectangular garden =l×b
77*50=3580
area of circular lake π×r2.
22/7×7^2=
154
area of circular lake /area of garden =
3580/154=
1/125 cm sq
