Question

radius 1S (b) If there is an error of 1% in measuring the side of a square plate, find the percentage error in its area. ​

Answer 1

Answer:

2%

Step-by-step explanation:

Let S is the side of the square plate.

Therefore the area is equal to S^2.

now formula for error calculation is equal to.

(a/A)*100=2*(s/S)*100

given s/S*100= 1%

therefore a/A*100= 2*1%

therefore a/A*100= 2%

the percentage error in area is 2%
