Hi, in my code, one answer is 8.049999999999999 SqM I know I could reduce to 8.05 and that would be great because say it was a program for working out measurements. I have seen toFixed(2) but I'm at a loss as to where to insert that, or is there a different method to use?
Any help, thanks.

function getArea(width, height, unit) {
var area = width * height;
var a = area.toFixed(2);
return `${a} ${unit}`;
}
console.log(getArea(10.2, 20.495, 'sq ft'));
Output: 209.05 sq ft

var num = 8.049999999999999;
var n = num.toFixed(2);

function getArea(width, height, unit) {
var area = width * height;
var a = area.toFixed(2);
return ${area} ${unit};
}

Full Stack JavaScript Techdegree Graduate 19,570 PointsNot sure what your doing with the return part, but try this simple example first:
function getArea(width, height, unit) {
var area = width * height;
var a = area.toFixed(2);
return a;
}
console.log(getArea(10.2, 20.495, 10));
Output was 209.05

10,338 Pointsreturn ${area} ${unit}; Is a template literal. Without them I cannot access units.

10,338 PointsYes I thought earlier that maybe on line var area = width * height; that maybe I could "get away" with adding .toFixed(2); I'm not against more lines of code, but I can see that line var area = width * height; has to declare the variable first.

But I spaced it out early to try and explain your issue.
