Question

the sides of a triangular plot of land are 375m, 500m and 625m. Find its area in are. If it is sold at ₹30,000 per are, how much amount will be realized on selling it (1 are=100 m²)

Answer 1

Answer:

5625000000

Step-by-step explanation:

Area of triangle =375×500×625=187500

cost =187500×30000=5625000000

Answer 2

Answer:

28,125,000 rupees

Step-by-step explanation:

Given :

• First side of the triangular plot = 375 metres = a

• Second side of the triangular plot = 500 metres = b

• Third side of the triangular plot = 625 metres = c

To find :

• Amount to be paid

Perimeter of the triangle = a+b+c = 1500 metres

Semi-Perimeter = Perimeter / 2

Semi-Perimeter = 1500/2

Semi-Perimeter = 750 metres

Area of a triangle by herons formula :

$\sqrt{s(s - a)(s - b)(s - c)}$

(s-a) = 375

(s-b) = 250

(s-c) = 125 metres

Area of triangle :

$\sqrt{750(375)(250)(125)}$

By solving, we get area = 93,750 m²

100 m² = 1 are

Area = 937.5 ares

Cost = 937.5×30,000

Cost = 28,125,000 rupees

The cost is equal to 28,125,000 rupees
