var perimeterBox = function(length, width) {

return length * width;

};

perimeterBox(1,2);

it says this doesn't return the correct perimeter (4) for a width of 1 and a length of 1.

# 9/13

First of all, since it's the perimeter, I returned length+length+width+width instead of length*width.

Also, I didn't add that last part over there.

With the two corrections, I think it'll work.

```
Perimeter of a rectangle = 2 * (length + width)
Area of a rectangle = length * width
```

We have to calculate the **perimeter**, not the area. So choose the correct formula.
