So the formula for area of a triangle is base * height / 2.
(In this case the height could be the altitude)
So if we rotate the shape, so line AC is the base, we can therefore clearly see what the height and length are.
If we count it, the line AC would equal 5 segments and the line BD would equal 3 segments.
So, 5 * 3 / 2
Or,
15/2
Which is 7.5.
So your answer is 7.5 square units.
6 tenths or 6/10
it doesn't matter how many zeros you have after the .6 it's still 6 tenths. It can have a hundred zeros it will still be just .6 = 6/10 = 6 tenths
Hope that helps you. :-)
