Question

Hey mates kindly help me with it....

It's an example of ncert but I am not able to understand it....

So kindly explain....​

Answer 1

Area of Triangle with sides

240 m, 200 m and 360 m for Wheat

s = (240 + 200 + 360)/2 = 400

Area using hero Formula

= √400 (400-240)(400-200)(400-360)

= √400 * 160 * 200 * 40

= 16000√2 m²

=1.6√2 hectare

= 2.26 Hectare

Area of Triangle with sides

240 m, 320 m and 400 m for onion & Potato

s = (240 + 320 + 400)/2 = 480

Area = √480 * 240 * 160 * 80

= 38400 m²

= 3.84 Hectare

Divided the field into two parts by joining the mid point of the longest side to the opposite vertex i.e Median

Median Divides the triangle into two equal area

= 3.84/2

= 1.92 Hectare

Potatoes = 1.92 Hectare

Onion = 1.92 Hectare

Wheat = 2.26 Hectare
