Answer:
441 
Step-by-step explanation:
If this is a rectangle, meaning the width and the legnth is different, there is no way in solving this.
However, if it is a square, meaning all the sides are the same,

An area is the width times the length, which is both 21 in this case.
21 times 21 = 441.
441 inches squared.
