The area of an equilateral triangle is ¼(√3a2) where "a" represents a side of the triangle. You are provided with the side "a". Find the area of the equilateral triangle.

my code is

// Getting input via STDIN

const readline = require("readline");

const inp = readline.createInterface({

input: process.stdin

});

const userInput = [];

inp.on("line", (data) => {

userInput.push(data);

});

inp.on("close", () => {

var data=userInput[0]

var data1=((0.43301)*(data*data))//start-here

//Your code goes here … replace the below line with your code logic

console.log(data1.toFixed(2));

//end-here

});
