Question

find the area of the triangle whose sides are 1.6cm, 3cm, and 3.4cm​

Answer 1

area of triangle by heron formula

Answer 2

Hey Mate, here's your solution using Heron's formula

Area of Triangle:

$a = 1.6 \: cm \\ b = 3 \: cm \\ c = 3.4 \: cm$

$s = \frac{a + b + c}{2} = \frac{1.6 + 3 + 3.4}{2} = \frac{8}{2} = 4 \: cm$

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

$= \sqrt{4(4 - 1.6)(4 - 3)(4 - 3.4)}$

$= \sqrt{4 \times 2.4 \times 1 \times 1.6}$

$= \sqrt{4 \times 3.84} = 2 \times 1.8 = 3.6 \: {cm}^{2}$

So, Area of Triangle = 3.6 cm²
