Answer 1

hope this will help you

Answer 2

Answer:

99.679 square units

Step-by-step explanation:

Sides of triangle :

a = 14 cm

b = 15 cm

c= 17 cm

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 :

$s = \frac{14+15+17}{2}$

$s =23$

$Area = \sqrt{23(23-14)(23-15)(23-17)}$

$Area =99.679$

Hence the area of the triangle is 99.679 square units
