Find for scalene triangles a=3,b=4 and c=5. Find Area

Solution:
Your problem `->` for scalene triangles a=3,b=4 and c=5. Find Area


`"Here " a=3, b=4, c=5" (Given)"`

`"Perimeter" = a + b + c`

`=3 + 4 + 5`

`=12`


`"Semi-Perimeter" = s = (a + b + c)/2`

`=12/2`

`=6`


`"Here " a=3, b=4, c=5" and " s = 6`

`"Area" = sqrt(s (s - a) (s - b) (s - c))`

`=sqrt(6 (6 - 3) (6 - 4) (6 - 5))`

`=sqrt(6 * 3 * 2 * 1)`

`=sqrt(36)`

`=6`
