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..
