Question

On a coordinate plane, the vertices of a rectangle are (-2,1), (3,1), (-1,-4), and (3,-4). what is the perimeter of the rectangle?

Answer 1

You can graph the points, then use the distance formula to find each side length. Then just add the sides together.
Distance formula:

`d = \sqrt{(x_2-x_1)^(2) + (y_2-y_1)^2 }`
