Question

1. are we likely to widen or shrink the margin of error if we convert from millimeters to feet squared.

the margin of error will remain the same.
neither, these units cannot be converted to one another.
widen.
shrink.

Explanation:

Millimeters are a linear unit (for length), while feet squared is an area unit (for two-dimensional space). Linear and area units measure different physical quantities, so they cannot be converted between each other.

Answer:

Neither, these units cannot be converted to one another.
