Area of Scalene Triangle
Perimeter
`(P) = a+b+c`
`S = P/2 = (a+b+c)/2`
Area
`(A) = sqrt(S (S  a) (S  b) (S  c))`
Example :
I know that for a scalene triangles a = 3 , b = 4 and c = 5 . From this find out Area of the scalene triangles.
`"Here " a=3, b=4, c=5" (Given)"`
`"We know that,"`
`"Perimeter" = a + b + c`
` = 3 + 4 + 5`
` = 12`
` `
`"SemiPerimeter" = s = (a + b + c)/2`
` = 12/2`
` = 6`
`"Here " a=3, b=4, c=5" and semiPerimeter" = 6`
`"We know that,"`
`"Area" = sqrt(s (s  a) (s  b) (s  c))`
` = sqrt(6 (6  3) (6  4) (6  5))`
` = 6`
