Question

the ratio of waist to height of a triangular field is three years to 1 the is the cost of cultivating the field at rupees 20 square metre is rupees 9050 find its base and height​

Answer 1

Answer:Let the height be a

Base = 3a

Cost of cultivating = Rs 9450.

Rate of cultivating = Rs 28 / m^2.

Area of field = Cost / Rate

Area of field = 9450 / 28

Base *Height /2 = 337.5 m^2

=> a * 3a = 675

=> 3a^2 = 675

=> a^2 = 225

=> a = 15 m

Height = 15 m

Base = 45 m
