Question

The area of a triangle having the sides 3cm, 4cm, 5cm? ​

Answer 1

Answer:

The area of the triangle is 6 centimeter square.

Step-by-step explanation:

Given : Triangle whose sides are 3cm ,4cm,5cm.

To find : The area of the triangle?

Solution :

Formula to find area of triangle is

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

Where, s is the semi perimeter,

$s = \frac{a+b+c}{2}$

a=3 ,b=4, c= 5 cm sides of the triangle

Substituting in the formula,

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

$s =\frac{12}{2}$

s = 6

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

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

$A = \sqrt{6.3.2.1}$

A = √36

A =6
