Question

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

Answer 1

Answer:

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.
