6×6−[4quarter circles r=2]−[3circles r=1]=  =36−7π
$$\mathrm{6}×\mathrm{6}−\left[\mathrm{4}{quarter}\:{circles}\:{r}=\mathrm{2}\right]−\left[\mathrm{3}{circles}\:{r}=\mathrm{1}\right]= \\ $$$$=\mathrm{36}−\mathrm{7}\pi \\ $$

Blue Area=2(2×4−π)+(4×4−π×2^2 )+(2×2−π)  Blue Area=(16−2π)+(16−4π)+(4−π)  Blue Area=16+16+4−2π−4π−π  Blue Area=36−7π  Blue Area=36−7×((22)/7)=36−22  Blue Area=14 cm^2
$$\mathrm{Blue}\:\mathrm{Area}=\mathrm{2}\left(\mathrm{2}×\mathrm{4}−\pi\right)+\left(\mathrm{4}×\mathrm{4}−\pi×\mathrm{2}^{\mathrm{2}} \right)+\left(\mathrm{2}×\mathrm{2}−\pi\right) \\ $$$$\mathrm{Blue}\:\mathrm{Area}=\left(\mathrm{16}−\mathrm{2}\pi\right)+\left(\mathrm{16}−\mathrm{4}\pi\right)+\left(\mathrm{4}−\pi\right) \\ $$$$\mathrm{Blue}\:\mathrm{Area}=\mathrm{16}+\mathrm{16}+\mathrm{4}−\mathrm{2}\pi−\mathrm{4}\pi−\pi \\ $$$$\mathrm{Blue}\:\mathrm{Area}=\mathrm{36}−\mathrm{7}\pi \\ $$$$\mathrm{Blue}\:\mathrm{Area}=\mathrm{36}−\mathrm{7}×\frac{\mathrm{22}}{\mathrm{7}}=\mathrm{36}−\mathrm{22} \\ $$$$\mathrm{Blue}\:\mathrm{Area}=\mathrm{14}\:\mathrm{cm}^{\mathrm{2}} \\ $$
