The minimum area bounded by the function 
$\mathrm{y}=\text{⨍ (x)}$ and $\mathrm{y}=\mathrm{\alpha x}+9(\mathrm{\alpha }\in \mathrm{R})$ where $\text{⨍ (x)}$ satisfies the relation $\text{⨍ (x+y)=⨍ (x)+⨍ (y)+y}\sqrt{\text{⨍ (x)}}\text{∀x, γ∈R}$ and ${\text{⨍ }}^1\text{(0)=0}$ is 9A. value of A is $\_\_\_\_\_\_\_$
