x, side of the given square
y, side of the other square

highlight_green%284x=12%2B4y%29, perimeter of a square is 12 cm greater than that of another square.
This equation can be simplified through division by 4:
highlight_green%28x=3%2By%29

The next description should mean "Its" refers to the given square of 4x perimeter.
highlight_green%28x%5E2=39%2By%5E2%29

You should find no trouble solving the system:
highlight%28system%28x=3%2By%2Cx%5E2=39%2By%5E2%29%29
