quants (Question:338245.0)

test 10 quest 10

Question:

If s=(a+b+c)/2 , then maximum area of a triangle formed by a,b, and c is:

Options:

$\frac{S^{2}}{2}$

$\frac{S^{2}}{4}$

$\frac{S^{2}}{8}$

$\frac{{2 S}^{2}}{3}$

Solution:

Area = $\sqrt{[s * (s - a) * (s - b) * (s - c)]}$ A.M. $\geq$ G.M.s + (s-a) + (s-b) + (s-c) $\geq$ 4* $\sqrt[4]{[s * (s - a) * (s - b) * (s - c)]}$ $\Rightarrow$ 4s - (a+b+c) $\geq$ 4* $\sqrt{A r e a}$ $\Rightarrow$ 2s/4 $\geq$ $\sqrt{A r e a}$ $\Rightarrow$ Area $\leq$ $\frac{S^{2}}{4}$
