Result

x = (Correct answer is: D)

Step-by-step explanation:

$$\begin{gathered} S=280\text{ mm}\to \text{ cm}=280\mathrm{/}10\text{ cm}=28\text{ cm } \\ C=56\text{ cm } \\ G=81.3\text{ cm } \\ B=635\text{ mm}\to \text{ cm}=635\mathrm{/}10\text{ cm}=63.5\text{ cm } \\ M=38\text{ cm } \\ D=61\text{ cm } \\ m=max(S,C,G,B,M,D)=max(28,56,81.3,63.5,38,61)={\displaystyle \frac{813}{10}}=81\frac{3}{10}=81.3\text{ cm } \\ G>B>D>C>M>S \\ x=D \end{gathered}$$
