Question

Farmer Kishan owns a triangular field with sides 120 m, 170 m and 250 m. He wants to fence it and grow wheat over the whole area. Find the area of the field (in m^2).

Accepted Answer

9000. s = 120+170+250/2 = 270. Area = √270 · (270-120) · (270-170) · (270-250) = √270 · 150 · 100 · 20 = √81000000 = 9000 m^2.
