Question

the base of a triangular field is three times its altitude. if the cost of levelling the field at rs 30.50 per sq. metre is rs 7350, find its base and height​

Answer 1

Answer:

38.025m, 12.675m

Step-by-step explanation:

Area=7350/30.50=240.9836

Let the base and height be x and 3x respectively.

Then, 1/2*x*3x=240.9836

=3x^2/2=240.9836

=3x^2=240.9836*2=481.9672

=x^2=481.9672/3=160.6557

=x=√160.6557=12.675

=3x=3*12.675=38.025
