let its height be x
then, base = 4x
Area of the triangular field = 1/2*x*4x = 2x²
according to question,
cultivating the field at per metre square = 450
total costs = 8100
2x²*450 = 8100
2x² = 8100/450
x² = 18
x = 4.24
height of triangular field = 4.24 units
while,
The base of triangular field = 4.24 x 4 units = 16.96 units.
then, base = 4x
Area of the triangular field = 1/2*x*4x = 2x²
according to question,
cultivating the field at per metre square = 450
total costs = 8100
2x²*450 = 8100
