Answer: The perimeter of the original square is the sum of the lengths of all its sides, which are all equal to 10 units:
Perimeter of original square = 4 x 10 = 40 units
When the square is enlarged by a scale factor of 2.2, all of its sides will be multiplied by 2.2:
New side length = 2.2 x 10 = 22 units
The perimeter of the new square is the sum of the lengths of all its sides, which are all equal to 22 units:
Perimeter of new square = 4 x 22 = 88 units
Therefore, the perimeter of the new square is 88 units.
