A house wife ordered 1.75cm material for a table cloth.if the actual measurements was 1.67cm , calculate the percentage error ?

To calculate the percentage error, we first need to find the difference between the ordered material and the actual measurements:

1.75 cm - 1.67 cm = 0.08 cm

Next, we calculate the percentage error by dividing the difference by the ordered material and multiplying by 100:

Percentage Error = (0.08 cm / 1.75 cm) * 100
Percentage Error = 0.0457 * 100
Percentage Error = 4.57%

Therefore, the percentage error in the measurements of the table cloth is 4.57%.

1. Calculate the absolute error:

Absolute error = Actual measurement - Ordered measurement
Absolute error = 1.67cm - 1.75cm
Absolute error = -0.08cm

(Note: The negative sign indicates that the actual measurement was less than the ordered measurement.)

2. Calculate the percentage error:

Percentage error = (Absolute error / Ordered measurement) x 100%
Percentage error = (-0.08cm / 1.75cm) x 100%
Percentage error ≈ -4.57%

Therefore, the percentage error is approximately -4.57%.
