Question

Find the area of rectangle ABCD that has vertices point A (2,−5), point B (5,−5), point C (5,−1), and point D (2,−1) in square miles.

Answer 1

The length of the rectangle is the distance between points A and B, which is 3 miles. The width of the rectangle is the distance between points A and D, which is 4 miles. Therefore, the area of the rectangle is:

3 miles × 4 miles = 12 square miles
