Final answer:
The area of a triangle with a base of 166 mm and a height of 930.0 mm, when converted to meters, is 0.0772 m² to the correct number of significant figures.
Step-by-step explanation:
To find the surface area of a triangular prism, you must find the area of all the faces and sum them up. However, the provided information and questions seem to address only finding the area of a single triangle, not a triangular prism. Using the formula for the area of a triangle (1/2 × base × height), if the base is 166 mm and the height is 930.0 mm, you first convert the measurements to meters since the question asks for an answer in square meters. Therefore, the base is 0.166 meters and the height is 0.930 meters. Calculating the area, we get 1/2 × 0.166 m × 0.930 m = 0.07719 m². The correct answer, expressed to the proper number of significant figures, is 0.0772 m².
