Answer:
4
Step-by-step explanation:
The formula for a rectangle is base times height so if one side is 7 inches then you need to figure out what times seven equals 28, which would be four.
If one pair of sides is 7 inches and the area is length times width then the answer would be whatever you multiple by 7 to get 28, so it would be 4 inches for each of the other two sides.
