3 0

1 times 1 = 1
2 times 2 = 4
3 times 3 = 9
4 times 4 = 16
5 times 5 = 25
6 times 6 = 36
7 times 7 = 49
*Special info: If you subtract 4 - 1, 9 - 4, 16 - 9,....,you'll get 3, 5, 7, 9, 11, 13, 15 and it easier to do that, just add 49 to 15 and you get 64, 8 times 8 = 64.

Answer: 40.5 square feet

Step-by-step explanation:

Given : Zhi needs new flooring for her two laundry rooms.each room is 4.5 feet long and 4.5 feet wide .
