Question

The error in the measurement of the sides of a rectangle is 1% the error in the measurement of it's area is​

Answer 1

Answer:

Area formula is L. L

Explanation:

Hence A/A =1/100×1/100=2/100

Hence it is 2%

Answer 2

Answer:

2%.

Explanation:

Since, we know the formulae of the area is known to be length*breadth. So, the the error in the length and breadth separately will be L*B or deltaL + deltaB where the value of the length and breadth error are 1% respectively.

So, the error in the area will be 1+1= 2%. Since, there are no multiple or power of the variables hence the error will be same.
