Question 402317: A roof rises 1.4 feet vertically and 11.8 feet horizontally. What is the grade of the roof? The grade of the roof is _____% how do I begin to find the answer to this? Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! The grade or slope (m) of a roof is defined as:
In this problem the rise is given as 1.4 ft. while the run (horizontal distance) is given as 11.8 ft., so... This is the grade of the roof.
You may see this as a percent, so multiply by 100. which would probably be rounded up to 12% grade.
