Question

the base of a triangular field is three times its height if the cost of cultivating the field at Rs 36 per hattrick is rupees 486 find its base and height 1 hectare is equal to 10000 metre square

Answer 1

Answer:

900

Step by step explanation:

let the altitude be=x

let the base be=3x

area of triangle=1/2×basex ht

area of triangle=1/2(x)×(3x)

area of triangle=3/2 x square

cost of cultivating=3/2x square×36=54x square.

therefore,486=54 x square

(1 hectare=10000m square)

486×100×100=4860000

4860000÷54=900

900=x square

hence x=300.

ht=x=300 and base=3x= 3×300=900.
