Question

The base of a triangular field is three times its height. If the cost of sowing the field at ₹64 per square metre is ₹ 864, then its base =​

Answer 1

Step-by-step explanation:

Since the cost of cultivating the field at at the rate of Rs. 36.72 per 100 square metre

is Rs. 49,572 => Area of the field =

36.72

49,572×100

=135000sqm

Now, area of the triangular field =

2

1

× base × height =135000

=>

2

1

×(3h)×(h)=135000

=>h

2

=90000

=>h=300m

And base =3×300=900m
