A triangular park in Pune has sides 50 m, 78 m and 112 m. The municipal gardener needs the area to plan grass turf. Using Heron's formula, find the area of the park (in m^2).

Question

Accepted Answer

1680. s = 50+78+112/2 = 120. Area = √120 · (120-50) · (120-78) · (120-112) = √120 · 70 · 42 · 8 = √2822400 = 1680 m^2.
