The error in its area is then 2 percent....
The percentage error in the area of the square will be twice the percentage error in the length of the square. This is because the error in the length affects both the length and width of the square, resulting in a compounded effect on the area. Therefore, if there is a 1 percent error in the length, the percentage error in the area would be 2 percent.

It means that the measured value is greater than the true value. Unless the experiment can be made error-free, that should happen around half the time.

Since the period of a simple pendulum (for short swings) in proportional to the square root of its length, then making the length one quarter of its original length would make the period one half of its original period.Periodapproximately = 2 pi square root (length/acceleration due to gravity)

area= side^2 let the symbol # denote error in measurement #area/area= 2(#length/length) #area/area*100= 2(#length/length)*100 percent error in area= 2*percent error in length=2% 2 per cent
Well, darling, when you make a 1% error in the length of a square, the percentage error in the area is technically 2%. It's simple math, honey. Just double the percentage error in length to get the percentage error in area. Easy peasy lemon squeezy.

Yes, your percent error can be over 100%. This means that somewhere during your experiment you made a big error.

It is a measure measurement of the amount of error made in an experiment. It is obtained by comparing the actual result, with the result gotten from the experiment. % error = [(experimental value - true value) / true value] x 100

You haven't said whether the error is 1% in each dimension, or 1/2% in each dimension, or whether the measurement is 1% too small, or whether it's 1% too big. In the arcane jargon of mathematics, this question would be characterized as 'sloppy'. -- If both the length and width are reported to be 1% shorter than they actually are, then the area will be calculated as 1.99% too small. -- If both the length and width are reported to be 1% longer than they actually are, then the area will be calculated as 2.01% too large. -- If one dimension is measured 1% too short and the other dimension is measured 1% too long, then the area will be calculated as 0.01% too small.
