The picture is not clear enough to read the numbers,
but it IS clear enough to see what's actually going on.
This page is not six different problems.
It's the same problem six times.
The problem is:
Find the area of a triangle, when you know
the height and the length of the base.
Here's the formula you need:
Area of a triangle = (1/2) · (length of the base) · (height) .
For each triangle, the picture gives the length of the base and
the height. All you have to do is write them into this formula, and
do the multiplication.
That's all the help you need. Go get um ! You can do it.
