Okay, don’t freak out. It’s more simple than it seems. To find the area of this rectangle you use length x length Let’s look for the length first Use the bottom left and right points (-2.25,-1) and (2.25,-1) The length is a horizontal line so we use the x-coordinates. The distance from -2.25 to 2.25 is 4.5 Now let’s find the height. Let’s use the top left and bottom left coordinates. (-2.25,4) and (-2.25,-1) The height is a vertical line. The y-coordinates. Their difference is 5. So 4.5 x 5 = 22.5
