Question

a triangular field is 3:1. if the cost of cultivating the field at rs 28 per sq. m is rs 9450, find its base and height.​

Answer 1

The answer is base is 675m and the height is 225m

Answer 2

Answer:

Let the height = a

Base = 3a

Cost of cultivating = Rs 9450.

Rate of cultivating = Rs 28 / m².

Area of field = $\frac{Cost}{Rate}$

Area of field = $\frac{9450}{28}$

$\frac{Base *Height}{2}$  = 337.5 m²

=> a * 3a = 675

=> 3a² = 675

=> a² = 225

=> a = 15 m

Height = 15 m

Base = 45 m

Still Doubt??
