New edge length of the resulting square becomes %28x-2%2A3%29=x-6.

Done in centimeter length units,
2%28x-6%29%2B2%28x-6%29=112, using perimeter formula.

2%28x-6%29=56

x-6=28

highlight%28x=34%29

New perimeter: 1.12 m, or 112 cm
Each side of new square: 112/4 = 28 cm
Length of each side before 3 cm was cut off: 28 + 3 = 31 cm
