Answer:
B
Explanation:
When we see "square inches" in a statement (or squared centimeters, meters, feet, etc) this refers to an area measure. So we need to find which of the options are areas.
A is not, as it is width, is a longitude measure. I could never be in square inches.
C is volume and it measure should be in cubic inches. So, not.
D is perimeter and is the sum if the lengths of different sides of a figure, so is also in inches, not square inches.
Finally, B is the area, so is our only chance. B in correct.
