The correct answer is B.
The perimeter of a square is 13cm. Therefore, one side of the square is \(\frac{13}{4}\) cm.
The perimeter of the equilateral triangle is 7cm. Therefore, one side of the triangle is \(\frac{7}{3}\) cm.
The difference of a side of the square and a side of a triangle is:
\(\frac{13}{4} – \frac{7}{3} = \frac{39-28}{12} = \frac{11}{12}\) cm
