A circular garden is surrounded by a fence of negligible width along the boundary. If the length of the fence is 1/4 of th area of the garden. What is the radius of the circular garden? Choose the correct choice from the following.
A) 1
B) 2
C) 4
D) 8
E) 16

Rationale: "as per the question - - width is negligible now , let l be the length of the fence = 2 pir l = 1 / 4 ( pir ^ 2 ) pir ^ 2 = 8 pir r = 8 answer : d"
Answer: D
