Answer 2

Here is your solution

$= \sqrt{s(s - a)(s - b)(s - c)} \\=\sqrt{48 \times 8 \times 24 \times 16} m {}^{2} \\\sqrt{16 \times 3 \times 4 \times 2 \times 4 \times 6 \times 4 \times 4} \\=4\times 4 \times 4 \sqrt{3 \times 2 \times 6} \\ =64 \sqrt{36} \\ =64 \times 6 \\ =384m^2$

I hope it helps you
