Question

the sides of traingle are 16cm,30cm,34cm find area

Answer 1

Hey mate!!!


Using Heron's Formula
Area =
$\sqrt{s(s - a)(s - b)(s - c)}$
where s = semi perimeter

Here s =
$\frac{16 + 30 + 34}{2} \\ = 40$
now applying the values in Herons formula
=
$\sqrt{40(40 - 16)(40 - 30)(40 - 34) } \\ = \sqrt{40 \times 24 \times 10 \times 6} \\ = \sqrt{40 \times 6 \times 24 \times 10} \\ = \sqrt{240 \times 240} \\ = 240$
240cm² is the area.

Hope it helps dear friend ☺️✌️✌️✌️
