THE REASON FOR ADDING THE 24 TO THE TRIANGLE IS BECAUSE IT IS 24 CM SHORT OF THE SQUARES PERIMETER THUS TO BALANCE THE EQUATION YOU MUST EITHER ADD THE 24 TO THE PERIMETER OF THE TRIANGLE OR SUBTRACT 24 FROM THE PERIMETER OF THE SQUARE SO THE TWO EQUATIONS ARE BALANCED.

THE 4 SIDES OF THE SQUARE ARE (X+4) AND THE 3 SIDES OF THE TRIANGLE ARE X.
THEN THE PERIMETER OF THE SQUARE IS 4(X+4) OR 4X+16 & THE PERIMETER OF THE
TRIANGLE 3X & THE SQUARE 4X+16=3X+24 OR 4X-3X=24-16 OR X=8
TRINGLE SIDES=8 & THE SQUARE SIDES ARE 8+4=12
PROOF 3*8=24 PERIMETER OF THE TRIANGLE & 4(8+4)=4*12=48 & 48-24=24 THE
DIFFERENCE IN THE TWO PERIMETERS.
