#16cm^2#

The area of a triangle can be found from the formula:

#A = (bh)/2" "rarr# b = base and h = height

The height is the same as the perpendicular height - look for the #90°# angle. It does not matter that the height is shown outside the triangle.

Turn the diagram upside down to see the base and the height.

We are given the base as #8cm# and the height as #4cm#

#A = (8xx4)/2#

#A = 16cm^2#

Units of area are always square units
