Question

find the area of a triangle with sides 5 6 and root 13 unit

Answer 1

$\sqrt{13} = 3.605$
use this value in herons formula and you will get the answer

Answer 2

Answer:

8.99 square units

Step-by-step explanation:

Sides of triangle :

a = 5

b =6

c = √13 = 3.605

To calculate the area of given triangle we will use the heron's formula :

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

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

a,b,c are the side lengths of triangle

Now substitute the values :

$s = \frac{5+6+3.605}{2}$

$s =7.3025$

$Area = \sqrt{7.3025(7.3025-5)(7.3025-6)(7.3025-3.605)}$

$Area = 8.99$

Hence the area of the triangle is 8.99 square units
