Question

calculate the area of a triangle whose sides are 80 CM 24 cm and 30 cm in length also find the length of the altitude corresponding to the smallest side

Answer 1

semi perimeter=18+24+30/2. a=18,b=24,c=30
=72/2=36
using heron's 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
=216cm2
