Answer:
20 cm^2
Step-by-step explanation:
I see two horizontal trapezoids here. Looking at the upper one, we see two different lengths: 7 cm and 3 cm; we also see that the width (measured vertically) is 2 cm.
The average length is (7 + 3)/2, or 5 cm.
Thus, the area of one trapezoid is (5 cm)(2 cm) = 10 cm^2, and the total area of both trapezoids is twice that, or 20 cm^2.
