The area is 96 square units.The length, x, of the base is __ units.

the best way to resolve this is by using the formula for the area of a triangle
[tex]A=\frac{x\cdot h}{2}[/tex]where A is the area, x is the base of the triangle, and h is the height
we know that A=96 square units, and h=9.6 units
then,
[tex]96\text{ sq units=}\frac{x\cdot9.6units}{2}[/tex][tex]\frac{(96sq\text{ units}\cdot2)}{9.6\text{ units}}=20units=x[/tex]The answer is x=20 units
