the error in the measurement it the side o a rectangle is 1% the error in the measurement it it's area is ​

Answer 1

Explanation:

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.
