The area of a playground is 1600 square metres. What is its perimeter ?
I. It is perfect square playground.
II. It costs Rs. 3200 to put a fence around the playground at the rate of Rs. 20/- per metre.
I : Since, playground is square, let the side = $$x$$ metres
=> Area = $$x^2=1600$$
=> $$x=\sqrt{1600}=40$$ metres
=> Perimeter = $$4\times40=160$$ metres
Thus, I alone is sufficient.
II :Â It costs Rs. 3200 to put a fence around the playground at the rate of Rs. 20/- per metre.
=> Perimeter = $$\frac{3200}{20}=160$$ metre
Thus, II alone is sufficient.
$$\therefore$$ Either statement alone is sufficient.
