Final answer:
To find the area of a trapezoid, use the formula ½ × (sum of bases) × height. Plug in the measurements to obtain an area of 26.04 m², which corresponds to option B.
Step-by-step explanation:
To calculate the area of a trapezoid, you use the formula: area = ½ × (base1 + base2) × height. In this case, the bases measure 5.5 meters and 6.9 meters, and the height is 4.2 meters.
Using the formula:
- Area = ½ × (5.5 m + 6.9 m) × 4.2 m
- Area = ½ × 12.4 m × 4.2 m
- Area = 6.2 m × 4.2 m
- Area = 26.04 m²
Therefore, the correct answer is B. 26.04 m².
