Answer 1

Answer:

384.375

Step-by-step explanation:

Length of the first side=150m Length of the second side=280m Length of the third side=410m Area of a triangle=S×S×S=150×280×410=15,375,000÷40,000=Rs.384.375. Therefore,the cost of per hectare=Rs.384.375

Answer 2

Answer:

s=a+b+c/2

150+280+410/2=420m

area= √s(s-a)(s-b)(s-c)

=√420(420-150)(420-280)(420-410) m²

√420×270×140×10m²

√158760000m²

=12600 m²

find price : 12600×4 = 50,400

1 hectare= 10,000so 1ha

like that 40,000hectare = 4ha
