Question

The area of triange whose sides are 4cm,3cm, and 5cm is,options : a)3cm b)12cm,c)6cm,d)8cm​

Answer 1

The area of triangle is 6 cm².

Option: (c)

Explanation:

Given: sides of triangle = 3cm, 4cm, 5cm.

We know that side of the triangle, S = $\frac{a+b+c}{2}$

S = $\frac{3 + 4+ 5}{2}$

= $\frac{12}{2}$

= 6 cm.

Hero of Alexendria, a Greek engineer, and a mathematician, named Heron's formulation in 10-70 AD. This formula can be used to find an area with three side lengths of a triangle.

Area of triangle, Heron's formula = $\sqrt{s(s-a)(s-b)(s-c)}$

= $\sqrt{6(6-3)(6-4)(6-5)}$

= $\sqrt{6 * 3 * 2 * 1}$

= $\sqrt{36}$

= 6 cm²

The area of triangle whose sides are 4cm, 3cm and 5cm is 6cm².
