Question

On a coordinate plane, trapezoid A B C D has points (negative 3, negative 2), (negative 1, 2), (3, 2), and (5, negative 2).
Trapezoid ABCD is graphed in a coordinate plane.

What is the area of the trapezoid?

16 square units
24 square units
32 square units
48 square units

Answer 1

The top base BC runs from (-1,2) to (3,2), so its length is 4. The bottom base AD runs from (-3,-2) to (5,-2), so its length is 8. The vertical height is 2 - (−2) = 4. Area = 1/2*(base1 + base2)*height = 1/2*(4+8)*4 = 24 square units.
