So, i'm completely lost on this. it's very easy to figure out as it's just writing a function, but i'm not entirely sure about the correct way to do so. i'd just like a standard f(w)= l*w type formula, if that's okay.

raj is making a rectangular garden for his dog cinnamon to play in. the length, l, of the garden is 2 yards greater than its width, w, in yards. enter the function, f(w), which describes the area, in square yards, of raj’s garden as a function of the width, w.
