**Answer: Option B**

**Explanation:**

Let us assume;

s is the side length of the square

r is the radius of the circle.

Perimeter of square = 4s

Perimeter or circumference of Circle = 2*π r*

From the given information we can write;

4s = 2*π* r.

Therefore;

s=*π* r/2. ——–(1)

Now we know;

Area of square = s^2 &

Area of circle = *π* r^2

Substituting value of s from (1) we get;

s^2 = *π* ^2 x r^2/4 – – (a)

and

the area of the circle *π* x r^2. – – (b)

Now to compare let’s just equate them to know which one has the larger area.

Now, let’s say, (a) = (b)

Area of Square = Area of Circle

*π* ^2 x r^2/4 = *π* x r^2

(r^2 and a *π* gets cancelled on both sides)

We get,

*π* /4 = 1

As we know that,

*π* /4 is less than 1

*π* /4 < 1

Hence, Area of Square < Area of Circle.

Thus, the area of Circle is greater.

So, Option (B) is right.
