Question

Find the area of the triangle whose side are 13,12,5cm​

Answer 1

Answer:

Given, the sides of a triangle are 5cm,12cm and 13cm

semi−perimeter =

2

a+b+c

s=

2

(5+12+13)

s=

2

30

s=15cm

Area of the triangle (according to the Heron's Formula)

=

s(s−a)(s−b)(s−c)

=

15(15−5)(15−12)(15−13)

=

15(10)(3)(2)

=

900
