A trapezoid has bases that measure 10 cm and 6 cm. The height of the figure is 15 cm. What is the area of the trapezoid?

ololo11 [35]

Answer: 120 cm.

Step-by-step explanation: First, add the two bases together (10+6) and you'll get 16. Then, multiply the height with the sum of the two bases (15 x 16) and you'll get 240. Now, multiply it with 1/2 (or divide by 2) and you'll get 120. So, 120 cm. is your answer.
