The area of playground is 1600 m2. What is the perimeter?

I. 

It is a perfect square playground.

 II. 

It costs Rs. 3200 to put a fence around the playground at the rate of Rs. 20 per metre.

I alone sufficient while II alone not sufficient to answer
II alone sufficient while I alone not sufficient to answer
Either I or II alone sufficient to answer
Both I and II are not sufficient to answer
Both I and II are necessary to answer
Answer: Option
Explanation:

Area = 1600 m2.

 I. Side = 1600 m = 40 m. So, perimeter = (40 x 4) m = 160 m.

I alone gives the answer.

II. Perimeter = Total cost = 3200 m = 160 m.
Cost per metre 20

II alone gives the answer.

Correct answer is (C).

In statement II the shape of the ground is not mentioned if the play ground is not in any geometric shape then how the perimeter can be determined?

Correct answer is option A.

Because in second statement the shape of ground is not mentioned. Then how is it possible to find its perimeter?

How A? @Manoj.
Kumar Dash said:   2 years ago
In case of the perimeter, the shape of the ground is not important. Because the perimeter is just a length. We can find the perimeter just by dividing the total cost by the cost per meter.
