Solution

297 square feet. Sample response: I know that 11 yards is 33 feet so the area is $9 \times 33$ feet. I know $9 \times 3 = 27$ and $9 \times 30 =270$ and $27 + 270= 297$ .

Problem 2

Tyler scored 126 points in 9 basketball games.

If Tyler scored the same number of points each game, how many points did he score in each game? Explain or show your reasoning.
Diego scored 5 more points than Tyler did in each game. How many points did Diego score in the 9 games? Explain or show your reasoning.

Show Solution

Solution

14 points. Sample response: I know that $10 \times 9 = 90$ and $4 \times 9 = 36$ and $90 + 36 = 126$ . So I added 10 and 4.
171 points. Sample response: $126 + (9 \times 5) = 126 + 45 = 171$ .
