Answer 1

Answer:

Find the area of a triangular field whose sides are 715m,660m and 285m .also find the cost of reaping it at the rate of ruppes50 per hectare.

Sides of triangular field are 715m,660m and 285m .

Rate = 50 / hectare

1 hectare = 1000 m²

1 hectare = 1000 m² s = 415 + 660 + 285 / 2

1 hectare = 1000 m² s = 415 + 660 + 285 / 2= 830

Formula of Area :-

√s + (s-a ) (s-b) (s-c)

Putting the value in Formula :-

= √ 830 ( 830-715) (830-660) (830-285)

= 29738 m

We know that ,

= 1 hectar = 1000 m²

= 1 m² = 1/1000 hectare

= ₹ 1486

Answer is ₹1486
