3 quarters of a circle if r=6m plus 2 quarter  circles of r=2m  (3/4)×6^2 π+2×(1/4)×2^2 π=29πm^2

$$\mathrm{3}\:\mathrm{quarters}\:\mathrm{of}\:\mathrm{a}\:\mathrm{circle}\:\mathrm{if}\:{r}=\mathrm{6}{m}\:\mathrm{plus}\:\mathrm{2}\:\mathrm{quarter} \\ $$$$\mathrm{circles}\:\mathrm{of}\:{r}=\mathrm{2}{m} \\ $$$$\frac{\mathrm{3}}{\mathrm{4}}×\mathrm{6}^{\mathrm{2}} \pi+\mathrm{2}×\frac{\mathrm{1}}{\mathrm{4}}×\mathrm{2}^{\mathrm{2}} \pi=\mathrm{29}\pi{m}^{\mathrm{2}} \\ $$
