if the rectangle is 3 wide, then u subtract 3 twice from the perimeter 28. then you divide by 2 to get the length of one side of the rectangle: 28-3= 25-3= 22/2= 11 or 28-6= 22 22/2=11 so the answer is 11

Perimeter = 154 mm = 15.4 cmArea = 1,372 mm2 = 13.72 cm2
This is so simple: 2 x (28 + 15) = 86 cm.
