Area = 18 units

#### Explanation:

The given triangle is sketched as in the figure above. Angle B would be

Side b is 12. It is the hypotenuse because it is opposite the right angle B.

For area, base and altitude is required. In this case it is side 'a' and side 'c'.

Side 'c' =

Side 'a' =

Area =

=

Area = 18 units.
