Question

calculate the area of the triangle whose sides are 18 cm 24 cm and 30 cm in length also find the length of the altitude corresponding to the smallest side

Answer 1

The answer is216 cm square

Answer 2

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
