	$A = a r e a$ $A = \frac{10 a}{2} = \frac{12 b}{2} = \frac{15 c}{2}$ $\Rightarrow a = \frac{A}{5}, b = \frac{A}{6}, c = \frac{A}{7.5}$ $s = \frac{1}{2} (\frac{A}{5} + \frac{A}{6} + \frac{A}{7.5}) = \frac{A}{4}$ $A = \sqrt{\frac{A}{4} (\frac{A}{4} - \frac{A}{5}) (\frac{A}{4} - \frac{A}{6}) (\frac{A}{4} - \frac{A}{7.5})}$ $1 = \frac{A \sqrt{7}}{240}$ $\Rightarrow A = \frac{240}{\sqrt{7}} \Rightarrow a n s w e r b)$
