A rectangle is shown on a coordinate plane with vertices A(Negative 4, 8), B(1, 8), C(1, Negative 1), and D(Negative 4, Negative 1).

On a coordinate plane, a rectangle has 4 points. Point A is (negative 4, 8), point B is (1, 8), point C is (1, negative 1), point D is (negative 4, negative 1).

What are the dimensions of the rectangle?
The base is 4 units and the height is 9 units.
The base is 5 units and the height is 7 units.
The base is 5 units and the height is 9 units.
The base is 9 units and the height is 3 units.

Answer: The base is 5 units and the height is 9 units.

Explanation:

Find the distance between each point:

Base can be calculated as the distance from A to B: Since y-coordinates are the same, subtract the x-coordinates: | - 4 - 1 | = 5

Height can be calculated as the distance from B to C: Since x-coordinates are the same, subtract the y-coordinates: | 8 - (-1) | = 9

Remember its distance, and that can't be negative, so take the absolute value of the results
