Answer:
Step-by-step explanation:
Let's assume that the length of a side of Allison's room as x
So, Lindsey's room = x + 3
If Lindsey's room needs 225 sq. feet of carpeting, then x + 3 = 
So, x + 3 = 15
Therefore, x = 15 - 3 = 12 ( So, Allison's room has a side of length 12)
Therefore, the carpeting needed = 12 × 12 = 12² = 144 sq. feet
There's your answer!
