Solution

The correct option is A 2.19991×108 inches2
We can find the difference between the areas of the nets by subtracting the small net's area from the big net's area.

Difference in area
= Area of the big net - Area of the small net
= 2.2 × 1080.9 × 104
= 22000 × 1040.9 × 104
= (220000.9) × 104
= 21999.1 × 104
= 2.19991 × 108

Therefore, the area of the floor is 2.19991 × 108 inches2.
