Q. The actual dimensions of a rectangle are 6 in by 4in. Carter measures the sides to be 5.75 in by 3.59in. In calculating the area, what is the relative error, to the nearest hundredth.Answer:
Calculate Actual Area: Calculate the actual area of the rectangle using the actual dimensions.The formula for the area of a rectangle is length×width.Actual area = 6in×4in=24in2.
Calculate Measured Area: Calculate the measured area of the rectangle using the measured dimensions.Measured area = 5.75in×3.59in.Let's perform the multiplication to find the measured area.Measured area = 20.6425in2.
Calculate Absolute Error: Calculate the absolute error by subtracting the measured area from the actual area.Absolute error = Actual area - Measured area.Absolute error = 24in2−20.6425in2.Absolute error = 3.3575in2.
Calculate Relative Error: Calculate the relative error by dividing the absolute error by the actual area.Relative error = Actual areaAbsolute error.Relative error = 24in23.3575in2.Let's perform the division to find the relative error.Relative error ≈0.1398958333.
Convert to Percentage: Convert the relative error to a percentage and round to the nearest hundredth.Relative error (as a percentage) = Relative error ×100.Relative error (as a percentage) ≈0.1398958333×100.Relative error (as a percentage) ≈13.99%.
