Question

the base of a triangular filed is three times it's height . if the cost of cultivating the filed at rupees 36per hectare is rupees 486,find it's base and height.​

Answer 1

Answer:

Step-by-step explanation:

We know that  

area of triangular field = cost of sewing field/ Rate of sowing = 783/58 = 13.5 hectare

1 hectare = 10000 m2

13.5 hectare = 135000 m2

Area of triangular field = 13.5 hectare = 135000 m2

Let altitude of triangular field be h.

The base of a triangular field is three times its altitude.

Hence, base of triangular field = 2h

Area of field = 1/2 bh

1/2 3h2  = 135000

we get h = 300  

Hence, altitude = h = 300 m

base = 900 m
