Answer: w x h = Area
Step-by-step explanation:
If you had a square and the left and right side was 3, that is the width. Then, if you have on the top and bottom lines, that is the height. You multiply one of the widths (3) and one of the heights (3) and in this case you would get:
w x h = area
3 x 3 = 9
Area= 9
