1.	77 m50 mLength and breadth of a rectangular garden are 77 m and 50 m. There is a circular lake in thegarden having diameter 14 m. Due to wind, a towel from a terrace on a nearby building fellinto the garden. Then, find the probability of the event that it fell in the lake.
Answer» Probability = favorable event/ total eventin this case favourable event is that lake and total event is the area of the square so we will do accordinglyarea of that lakeπr^2=7x710= 49πand total area of square = 7750mxm3850 m^2probability = 49π/38500.03
