Answer 1

find the area of a triangular field whose sides are 275m, 660m and 715m. what is the cost of cultivating the field at the rate of 200 per hectare?

we check the nature of the triangle,

715²=511,225

275²+660²+ 511 225

the triangle is right

Area =(275*660)/2=90750m² = 9.075 hectares

cost of cultivating the field: 9.075*200=1815 (you did not put the currency $ or other but the cost whatever the currency is 1815)
