Question 892025
Area = {{{1/2}}}b*h
Area = 27cm^2, so b*h = 54
Factors of 54 are:
54,1
27,2
18,3
9,6
6,9
3,18
2,27
1,54
Which of those fits the equation B=2H-3?
If (27,2), then 27 = 2(2)-3.  Nope, that doesn't fit.
(18,3) 18 = 2(3)-3.  That doesn't work either.
(9,6) 9=2(6)-3.  Success!  The base is 9 and the height is 6
