#1**0 **

Hello Guest,

To solve this problem, we can first use the distance formula. Find the length of the sides first.

(Hint: If you don't know the distance formula, it is: \(d=\sqrt{(x2-x1)+(y2-y1)}\)

Then, using the side lengths, you can apply the formula of b*h where b is the base, and h is the height to the rectangle and find the area. Please let me know if you need more help!

This requires finding the DISTANCE between two points. Using the distance formula, for (1,5) and (3,4), we get $\sqrt {5}$, and we also get for (3, 4) and (0, -3) by the distance formula $\sqrt {58}.$ Then we multiply the length times width, $\sqrt{290}$, which cannot be simplified.
