The area of a square is just side times side. So 3 * 3 = 9.
There are 4 half-circles which is the same as 2 full circles. Area of a circle is pi * the radius squared or

.
So we do 2(pi * (1.5)²) >> 2(2.25pi) = 4.5pi.
Now we add our two areas together. So the area of the whole thing is represented by the equation 4.5pi + 9. Plug this into a calculator to get your accurate measurement.
4.5pi + 9 ≈
23.137 m²
