What makes it difficult to you to solve it on your own?

The area of the circle is pi%2Ar%5E2, everybody knows it.

The area of 6 circles that are not overlay each other is 6 times the area of one circle.

May be, you don't know what is the area of a rectangle?
Then why do you try to solve such complex problem?
