The length and breadth of a field are measured as (200+_5)m and (100+_4)m resp. What is the area of the field?

        A=L×B=200×100=20000       AA=LL+BBor      A20000=520+4100=13200or        A=20000×13200=1300So the area =A±A=20000±1300

As the length and breadth are given, thus it means that the field is in the shape of a rectangle and hence its area will be given as, area =length * breadth

Now, length of field= (200 plus minus 5) metres

Breadth of field = (100 plus minus 4)

👉 area = {(200*100) + (5+4)} = (300 plus minus 9) metres


HOPE ITS CLEAR!! 😄
