A quart of stain covers 100 square feet. How many quarts should you buy to stain the ramp? (Assume you do not have to stain the bottom of the ramp.)

ik how do do this just give me a few minutes and i will give it to

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
