6-year-old mathematics practical problems Use several squares with unit length of 1 to make a rectangle with area of 12. Q: what is the circumference of the rectangle? Please write all the possible answers
∵12=1×12
=2×6
=3×4
The circumference of a rectangle may be:
2×(1+12)=26
2×(2+6)=16
2×(3+4)=14
There are three possibilities: 26, 16 and 14
