Question

the base of a triangular field is three times its height if the cost of cultivating the field at rs 36 per hectare is rs 486 , find its base and height (1 hectare=10000m^2​

Answer 1

Answer:

Step-by-step explanation:

Area of field = 486/36

= 13.5 hectare

= 13..5 × 10000

=135000 metre sq

Now it is given that base of field is three times height

Let the height be x metre

Hence base = 3x

Area of triangle = 1/2 × base × height

=> 135000 =1/2 × 3x × x

3x square/2 = 135000

3x square = 135000 × 2

3 x square = 270000

x square = 270000/3

= 90000

x =√90000

x =300 m

Height =300 metre

Base =3x =3× 300

= 900 m

Hope it is clear
