Help w/ Area prob: 'The area of a rectangle is 119 m^2....'

I am dying here! Can someone help with instructions on how to solve this problem? I have 25 to do and I forget the formula, lesson, etc. Thanks.

The area of a rectangle is 119 m2. The base is four less than three times the height. What is the length of the base?

area is 119 ...
bh = 119

The base is four less than three times the height ...
b = 3h - 4

since bh = 119 and b = 3h - 4, then wouldn't the following equation be true?

(3h - 4)h = 119
