Question

Length and breadth of a rectangular garden are 77 m and 50 m. There is a circular lake in the garden having diameter 14 m. Due to wind, a towel from a terrace on a nearby building fell into the garden. Then find the probability of the event that it fell in the lake.

       

Answer 1

Area of the rectangular garden 

= length × breadth 

= 77 × 50 

∴ Area of the rectangular garden = 3850 

sq.m Radius of the lake = 14/2 = 7 m

∴ The probability of the event that the towel tell in the lake is 1/25.
