The area of rectangle ABCD is 17 square units

The area of the rectangle ABCD can be calculated using the formula for the area of a rectangle: Area = Width × Height

Width: The distance between points A and C, which is the same as the distance between points B and D. Since both the y-coordinates are the same for these points, the width is simply the difference in x-coordinates: |0 - (-1)| = 1.

Height: The distance between points A and B, which is the same as the distance between points C and D. Since both the x-coordinates are the same for these points, the height is simply the difference in y-coordinates: |9 - (-8)| = 17.

Therefore, the area of the rectangle ABCD is:

Area = 1 (width) × 17 (height) = 17 square units

So, the area of rectangle ABCD is 17 square units
