A) 6 inches. ( if the equation for the area of a triangle is
[tex] \frac{base \times height}{2} = area[/tex]
, insert 18 for area. also, since the base and height are the same length, substitute base x height for side ^2. then solve for side.
B) 4 and 9, 3 and 12, 18 and 2, and 36 and 1. (solve for all possible b×h)
