Question

What is the area of a rectangle with vertices at (1,7) (5,3) (3,1) and (-1,5)

Answer 1

The area of the triangle is 16.
You can find this by plotting each of the points and drawing the triangle. You can then use the distance formula to determine each side length. The rectangle will be 2
`√(2)` on one side and 4
`√(2)` on the other. When multiplied together, it will give you the above answer.
