Area of square = 9^2 =81  Area of given region is half of the square.  Area of given region=((81)/2)=40.5 units

$$\mathrm{Area}\:\mathrm{of}\:\mathrm{square}\:=\:\mathrm{9}^{\mathrm{2}} =\mathrm{81} \\ $$$$\mathrm{Area}\:\mathrm{of}\:\mathrm{given}\:\mathrm{region}\:\mathrm{is}\:\mathrm{half}\:\mathrm{of}\:\mathrm{the}\:\mathrm{square}. \\ $$$$\mathrm{Area}\:\mathrm{of}\:\mathrm{given}\:\mathrm{region}=\frac{\mathrm{81}}{\mathrm{2}}=\mathrm{40}.\mathrm{5}\:\mathrm{units} \\ $$
