Find the area of a rectangle ABCD with vertices at point A(-3, 4), point B(1, 4), point C(1, 2) and point D(-3, 2) in square miles.
*
24 square miles
12 square miles
8 square miles
16 square miles
The length of the rectangle is the distance between points A and B, which is 4 units.
The width of the rectangle is the distance between points B and C, which is 2 units.
Therefore, the area of the rectangle is 4 units x 2 units = 8 square units.
Since 1 mile is approximately equal to 69.05 units, and the area is in square miles, we need to convert the area from square units to square miles:
8 square units x (1 mile / 69.05 units)^2 ≈ 0.0161 square miles
Therefore, the area of the rectangle ABCD is approximately 8 square miles.
Answer: 8 square miles
