Final answer:
The area of a triangle with a base of 166 mm and a height of 930 mm is 77190 mm² when calculated using the formula for the area of a triangle, and expressed with the appropriate number of significant figures.
Step-by-step explanation:
The area of a triangle is calculated using the formula: area = 1/2 × base × height. For a triangle with a base of 166 mm and height of 930.0 mm, the area in square millimeters would be calculated as follows:
- First, we multiply the base by the height: 166 mm × 930.0 mm = 154380 mm².
- Then, we multiply by 1/2 to find the area: 1/2 × 154380 mm² = 77190 mm².
Since both the base and the height are given with more than one significant figure, our final answer should reflect this precision. We express our answer with five significant figures, which is 77190 mm².
