Answer 2

HEY MATE HERE IS YOUR ANSWER

We can use HERONS FORMULA here

$area \: of \: triangle \\ = \sqrt{s(s - a)(s - b)(s - c)}$

$where \: is \\ s = \frac{a + b + c}{2}$

$\\ given \: a = 13 \: \: b = 14 \: \: c = 15$

$s = \frac{13 + 14 + 15}{2} = 21$

$area = \\ \sqrt{21}(21 - 13)(21 - 14)(21 - 15)$

$a = 84$

$= \sqrt{21} (8)(7)(6)$

HERE THE AREA OF THE TRIANGLE IS 84sqm..
