Question

2/ The altitude and the base of a triangular field
are in the ratio 6:5. If its cost is 49,57,200
at the rate of 36,720 per hectare and
1 hectare = 10,000 sq. m, find (in metre)
dimensions of the field.​

Answer 1

Answer:

let base = 6x

height =5x

area of triangular field = 5x × 6x

=30x

cost of field at 36720 per hectare= 4957200

converting hectare into metre

36720÷10000=3.672m

cost of field at 3.672m= 3.672×30x

4957200=3.672×30x

4957200÷3.672=30x

1350000÷30=x

x=45000

base=6x=6×45000=270000

height=5x=5×45000=225000
