the base of a triangular field is 2.4 times the height, if the cost of levelling the field @ Rs 20 per sq. m is Rs 9600, find its base and height.

Answer:

doing

Let the height be H. Base = 2.4H

Area = half X base X height = 1.2H X H = 1.2H2

Cost of levelling is 9600 at Rs 20 per square meter.

Hence, area of the field = 9600 / 20 = 480 sq. m.

Hence, 1.2H2 = 480 

H2 = 400

H = 20 meter

Hence, base = 2.4 X 20 = 48 meter
