I would recomend using Desmos to plot the points to see the rectangle. When you plot it the rectangle seems to be rotated, so we will have to use pythagorean theorem to find the side lengths. Once you find the side lengths you multiple them and get about 30 square units.
Dividing the first equation by 2 X + 2y = 12 Dividing the equation 2 by 4 -3x + 2y = -4 subtracting both equations 4x = 16 X = 4 Also 4 + 2y = 12 2y = 8 Y = 4 Please mark as brainliest
