 A = (width) * (long)
 Substituting values we have:
 750 = (y-5) * (y)
 Rewriting we have:
 750 = y ^ 2 - 5y
 y ^ 2 - 5y - 750 = 0
 Answer:
 
An equation that can be used to solve for And the length of the room is:

In ΔABC, point M is the midpoint of side AB and point D is the midpoint of segment MC. Prove that the area of ΔADC= the area of
Anna11 [10]
A line segment from a vertex to the midpoint of the opposite side is a "median". A median divides the area of the triangle in half, as it divides the base in half without changing the altitude.
AAMC is half AABC. AADC is half AAMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
ABMC is half AABC. ABMD is half ABMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
Then, AADC = 1/4 AABC = ABMC, so AADC = ABMC by the transitive property of equality.
