Question

the base of a triangular field is twice its altitude is the cost of cultivating the field is rupees 14.50 100 m square is rs 52200 find its base and altitude

Answer 1

  Let the altitude be x
Then the base = 2x2x

Area of the triangular field= 1212bh = 12×2x×x=x212×2x×x=x2 ---(1)

cost of ploughing the field = Rs.18360
Rate = Rs.216 per hectare
=>Area of the triangular field = 18360216=8518360216=85 hectare = 8,50,000 sq.m ---(2)

From(1) and (2)
x2=8,50,000x2=8,50,000
=>x=921.95x=921.95 meter

height = x=921.95x=921.95 meter
base = 2x=1843.92x=1843.9 meter

Answer 2

Answer:

Step-by-step explanation:

Base of triangular field=52200÷14.50=3600

3600÷100=36

Let altitude be 2x

1/2×2x×x=x^2

=36×x/3=12

=12/2=6
