$11.99 Satisfied 123 Students 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 More math articles What people say about "Geometry Puzzle - Challenge 73"?
