How to find the area of a shaded region if there are two circles inside a square, the area of the square is 60 ( on side is 6 and the other is 10)?

If it's breadth is 6 then the circles should have the diameter 6 and radius = 3
now subtract the area of both circles from the area of rectangle
area of circle = π r²
= 3.14 x (3)²
= 3.14 x 9
= 28.26
this is area of one circle 
so area of both circles = 2 x 28.26 = 56.52
now the area of shaded region = area of rectangle - area of both circles
area of shaded region = 60 - 56.52
                                = 3.48 <ANSWER
