Final answer:
To find the area of a shaded triangle in square inches, use the formula (1/2 × base × height) and convert from square meters to square inches if necessary, keeping significant figures in mind.
Step-by-step explanation:
To calculate the area in square inches of the triangular region that has been shaded in a given figure, you can use the formula for the area of a triangle: Area = 1/2 × base × height. If the base and the height of the triangle are given in meters and you need the area in square inches, you will also need to convert from square meters to square inches using the conversion factor that 1 square meter is approximately 1550 square inches.
We would first multiply the base by the height, then divide by 2 to find the area in square meters, and finally multiply by 1550 to convert to square inches. If the dimensions are given in different units, make sure they are converted to the same unit before applying the formula. Remember to express the final answer to the correct number of significant figures based on the precision of the measurements given.
