Question

The sides of a triangular field are 75m, 100m and 125 m. If this field is sold at the rate of Rs. 1000 per m2, find its selling price.pls tell correct answer​

Answer 1

Answer:

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
