Answer:
132 cm^2
Step-by-step explanation:
First find the area of the rectangle on top:
4 * 7 = 28 cm^2
Remember: Don't forget units!
Next, find the average of the trapezoid's bases:
(7 + 19) / 2 = 26 / 2 = 13
Then, find the area of the trapezoid using (avg(bases) * height):
13 * 8 = 104 cm^2
Finally, add the two areas:
28 + 104 = 132 cm^2
