Answer:
Step-by-step explanation:
Area of the triangle=s.(s−a)(s−b)(s−c)
(by heron's formula)
where s=2(a+b+c)
a=975m, b=1050m, c=1125m
∴s=1575m
Area=1575(1575−975)(1575−1050)(1575−1125)
⇒472500m2
1hectare=10,000m2
∴472500m2=47.25hectares
⇒ selling price of the field will be 47.25hectares×1000
⇒=47250Rs
