semi perimeter (s) =(13+14+15)/2=42/2=21 m,
then
Area of the ∆=√[21(21-13)(21-14)(21-15)],
=√[21×8×7×6],
=√(3×7×2×2×2×7×2×3),
=3×7×2×2,
=84 m²
then
Area of the ∆=√[21(21-13)(21-14)(21-15)],
=√[21×8×7×6],
=√(3×7×2×2×2×7×2×3),
=3×7×2×2,
=84 m²

A triangle which has side,
a = 13 m
b = 14 m
c = 15 m
And,
Semi perimeter (S) = 21 m
We can find the area of triangle by the heron's formula.
Hence,
Area of triangle = 84 m²
