Question

Length and breadth of a rectangular garden are 77m 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

Answer:

• The probability of the event that it fell in the lake is 1/25

Step-by-step explanation:

Given:

• Length and breadth of a rectangular garden are 77m and 50 m.
• Diameter of circular garden = 14 m

To Find:

• The probability of the event that it fell in the lake

Solution:

Area of Rectangle = L × B

➞ 77 × 50

➞ 3850 m²

Now,

• Diameter of circle = 14 cm
• Radius = 14/2 = 7 m

Area of circle = πr²

➞ 22/7 × 7 × 7

➞ 22 × 7

➞ 154 m²

Required probablity = 154/3850

Hence,

• The probability of the event that it fell in the lake is 1/25
