Question

The coordinates of a rectangle are (-11,20), (-11,3), (-1,20), (-1,-3). Find the perimeter and the area of the rectangle.

Answer 1

The perimeter of the rectangle is 54, and the area is 170.

Explanation:

First, we must plug the coordinates into a graph (attached below).

`l=10\\w=17`

Now, we must solve for the perimeter.

`P=2(l+w)\\P=2(10+17)\\P=2*27\\P=54`

Lastly, we must solve for the area.

`A=wl\\A=(17)(10)\\A=17*10\\A=170`

You're welcome!
