Final answer:
To calculate the area of a shape, use the correct formula and round the result to the appropriate number of significant figures, ensuring the units are square meters.
Step-by-step explanation:
To find the area of a shape, we use different formulas depending on the type of shape. In the question, there is a missing shape description, but we can consider several scenarios:
For a rectangle or square, we multiply the length by the width (area = length × width).
For a circle, we use the formula area = πr², where r is the radius of the circle. If we use 3.14 as an approximation for π, and the radius is given, we can substitute these values into the formula to calculate the area.
For a triangle, the formula is area = 1/2 × base × height.
When expressing the answer in square meters, remember that the final answer should be in line with the number of significant figures of the given dimensions. For example, if you calculated an area to be 4.5238934 m² with a calculator, but the given measurement had two significant figures, you would round the result to 4.5 m².
In summary, when calculating the area, use the appropriate formula for the shape, ensure the units are consistent, and round the final answer to the correct number of significant figures.
