In order to solve this problem, we need to find the length of a width, and a length of the long side.

To find how long the width is, we use the distance formula on the points (2,-3) and (5,-1).

This is
width = \sqrt{(5-2)^(2)+(-3-(-1))^(2) } = √(13) = 3.6

Now, we find how long the length is. We do this the same way:


length = \sqrt{(5-1)^(2) (5+1)^(2) } = √(52) = 7.2

Now, we multiply 3.6 by 7.2 to get our answer. This is equal to 25.9, so this is the area.
