Find the area of a rectangle ABCD that has vertices point A (1,−4), point B (4,−4), point C (4, 0), and point D (1, 0) in square miles.

Answer 1

To find the area of the rectangle, we need to find the length of the base and the height.

The length of the base = DC = 4 - 1 = 3 miles
The height = AD = 0 - (-4) = 4 miles

Area = base x height
Area = 3 miles x 4 miles
Area = 12 square miles

So, the area of rectangle ABCD is 12 square miles.
