Final answer:
The area of the trapezoid is 80 square units.
Step-by-step explanation:
The area of a trapezoid can be found using the formula:
Area = 0.5 * (base1 + base2) * height
In this case, the bases are 7 and 9, and the height is 10. Plugging these values into the formula:
Area = 0.5 * (7 + 9) * 10
Area = 0.5 * 16 * 10 = 80
Therefore, the area of this trapezoid is 80 square units.
