1. Finding area in graph

Basically, the question states to find the area of a shape (form by line) in a graph, but my question is, what unit should I use? I know the steps, but what unit should my answer be?

The answer uses units of the graph

Thank you

Do you mean square centimeters or square inches? In these problems, lengths and areas don't have dimensions. If you have a graph, you have a coordinate plane and a unit segment on each axis. The question asks how many 1 x 1 squares (probably fractional number) can fit into the shape.

Erm, Say length Point A(-5,-0) to B(4,0) is 9units (one side of the triangle), then it's height is 10 units. So, 1/2 x 9 x 10 = 45, but what unit should I put? Or maybe there's not a need for it?
