height=x ,
base= 3x
Area of triangle =
 \frac{1}{2}  \times base \times height
 \frac{1}{2}  \times x \times 3x
 \frac{3}{2}  {x}^{2}
1 hectare =10000 sq metre
Rate of sowing of the field per hectare = rs 58
total cost of sowing of the field per hectare = 783

total cost = Area of triangle * rs 58
 \frac{3}{2}  {x}^{2}  \times  \frac{58}{10000}  = 783
 { x}^{2}  =  \frac{783}{58}  \times  \frac{2}{3}  \times 10000
 \sqrt{90000}
300m
height = 300m
base = 300*3
= 900 m
