12. Calculate the area and cost of the land

Alexa buy a land in the shape of an equilateral triangle. The perimeter of the land is 225 \(m\). Find the area of the land and find how much cost she spent to buy the land, if each square metre is \(₹\)18. (Use: \(\sqrt{3} = 1.73\))

 

Area of the land \(=\)  \(m^2\)

 

Amount spent to buy the land \(=\) \(₹\)

 

[Note: Round off the area up to two decimal places and round off the amount to the whole number.]
