Another Math Problem.

As i said before there's a couple problems, here is the other one. Feel free to comment or correct my calculations.


Building codes require the minimum slope, or pitch, of a roof with asphalt shingles to be such that it rises at least 4 feet for every 12 feet of horizontal distance. A 72 foot wide apartment building has a 12 foot high roof. Does it meet the building code? Explain.

The problem is suggesting that 4/12 = 12/72, to find if this is true i am going to put x in for 12 to check the answer.

4/12 = x/72
12x=288
x=24


The building does not meet the code because 4/12 does not equal 12/72.
In order for the building to be up to code the roof would have to be 24 feet high.
