(A) 1% (B) 1/2%
(C) 2% (D) None of the
above.​

Answer 1

Answer:

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%.

Answer 2

Answer:

2% of error is there in the measurement of its area....
