Final answer:
The area of a trapezoid is calculated using the formula which averages the lengths of the two parallel sides multiplied by the height. When calculating areas, converting units for consistency and expressing answers with correct significant figures are key steps.
Step-by-step explanation:
The question pertains to finding the area of a trapezoid. In mathematics, the area is the size of a two-dimensional surface. The information provided suggests that the area calculation is related to figures on a graph, commonly seen in coordinate geometry or physics contexts where areas under curves represent quantities like displacement. To find the area of a trapezoid, the formula is the average of the lengths of the two parallel sides (bases) times the height (distance between the parallel sides). The references to triangles and rectangles imply the area might be needed in separate components and then combined. Important is the notion of significant figures in the answer, reflecting precision based on the given measurements.
Let's use the information provided as an example to calculate the area of a triangle, which has a formula of 1/2 × base × height. Converting units where necessary to maintain consistency and expressing the answer to the correct number of significant figures is crucial for an accurate calculation.
