☆Hello friend☆

$\sqrt{s(s - a)(s - b)(s - c)} \\ s = \frac{a + b + c}{2}$
s= (39m+25m+56m)/2= 60m
$\sqrt{60(60 - 39)(60 - 25)(60 -56) } \\ \sqrt{60 \times 21 \times 35 \times 4} \\ \sqrt{2 \times 2 \times 3 \times 5 \times 3 \times 7 \times 5 \times 7 \times 2 \times 2}$
(2×2×3×5×7)m^2
420m^2

Hope it helps
