Question

The error in the measurement of
the sides of a rectangle is 1%. The
error in the measurement of its
area is..​

Answer 1

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%.
