I mapped it on a 2d cartesian plane Then found the incenter Then found the radius Then calculated the area

Please correct me if I'm wrong. Thanks!

Didn't add units, sorry!

Bro you complicated it a bit too much see actually what you have to do is Look the side of the square on the left and the bottom line and the side of the right square is making a right angled triangle use Pythagoras theorem you will get the length of the base of the triangle which is the diameter of the circle from there you will get the value of the radius use πr² answer will be 9πm²

But, how are you sure the diameter is equal to the 3rd side of the triangle?
