Question
What is the area of a rectangle with vertices at (4, 3), (11, 3), (11, 9), and (4, 9)?A.13 units2B.26 units2C.42 units2D.21 units2
Solution
The area of a rectangle is calculated by multiplying its length by its width.
In this case, the length of the rectangle is the distance between the points (4, 3) and (11, 3), which is 11 - 4 = 7 units.
The width of the rectangle is the distance between the points (4, 3) and (4, 9), which is 9 - 3 = 6 units.
Therefore, the area of the rectangle is 7 units * 6 units = 42 units^2.
So, the correct answer is C.42 units^2.
