(a) What is the angle subtended by CD at the centre O? (b) What is the distance between mango tree A and ashoka tree C? (c) Find ∠OCD

Answer 1

Answer:

Correct option is

A

24

Each row contains 12 plants.

There are 11 gapes between the two corner trees (11×2) metres and 1 metre on each side is left.

Therefore, length of the garden =(22+2)m=24m.
