Question

Find the cost of leveling the triangle field having its sides as 51m,37m and 20m at ₹12

per square metre​

Answer 1

Hey!!Hope this helps you....

length of the sides=51m,37m,20m

cost for levelling 1m square=Rs 3

∴ we need to find the area of the ground

=√s(s-a)(s-b)(s-c)

∴s=a+b+c/2

=51+37+20/2

=108/2

=54

∴area=√54(54-51)(54-37)(54-20)

=√54×3×17×34

=√93636

=306 square metres

∴cost for levelling the ground

=3×306

=918

Ans:-Rs 918 are required to level the ground.
