Final answer:
Sona knits 10 squares a day for 7 days, resulting in a total of 70 squares. To make 5 equal-sized blankets, she needs to sew together 14 squares for each blanket.
Step-by-step explanation:
Given that Sona knits 10 squares a day for 7 days, we can find the total number of squares she knits by multiplying the number of squares she knits per day by the number of days. So, Sona knits a total of 10 squares/day * 7 days = 70 squares.
To determine if she can make 5 equal-sized blankets, we need to find the number of squares required for each blanket. Since we want 5 equal-sized blankets, we divide the total number of squares by 5. Therefore, each blanket would require 70 squares / 5 blankets = 14 squares per blanket.
To make 5 equal-sized blankets, Sona would need to sew together 14 squares for each blanket.
