s = 1/2 (a+b+c )
1/2(18+24+30) = 36
area of triangle =√s(s-a) (s-b) (s-c)
√36 *(36-18) (36-24) (36-30)
√36 *18*12*6
√46656
216 is the ans :)

Hey !!!
let side of triangle a = 18 b = 24 and c = 30
By using herons formula
s = 1/2 {a + b + c) = 1/2(18+24+30)
= 1/2(72) = 36
so , herons formula
= √ s (s-a) (s-b)(s-c)
= √36(36-18)(36-24)+(36-30)
= √36×18×12×6
= √2×2×3×3×3×3×2×2×2×3×2×3
= 2×2×2×3×3×3
= 216cm³ Answer
~~~~~~~~~~~~~~~~~~~~~~~~~~
Hope it helps you !!!
