Area: 3.14 * 3 2 = 28.26 square meters.
If the area on the map is calculated first, it is: 3. 14 * 1.5 2 = 7.065 square centimeters.
The actual area is 7.065 * 200 2 = 282600 square centimeters =28.26 square meters.
The exact answer ... you have miscalculated. ...

Actually, you can do anything. If the actual distance is calculated first, the area will be more natural. Just multiply the actual length by the width. ...
If you calculate the area on the map first, then calculate it directly and multiply it by the square of the reciprocal of the scale. ...
I hope my answer will satisfy you.
