Hii, ur answer is here....

Step-by-step explanation:

sides of triangle are 11cm,8cm,13cm.

  • semi perimeter = side + side + side/2 .
  • semi perimeter = 11+8+13/2 = 16.
  • now, we using heron formula,

area of triangle = √s( s-a) (s-b) (s-c).

= √16(16-11) (16-8) (16-13)

= √16×5×8×3

= √2×2×2×2×5×2×2×2×3

= 2×2×2×√30

= 8√30cm..
