ason drew a square with a side length of 8 cm. Bella drew a rhombus with a side length of 8 cm. Jason says the perimeter of the square is smaller than the perimeter of the rhombus. Bella says they have the same perimeter. Which of them is correct and why?

Answer 1

Jason is correct. The perimeter of a square is calculated by multiplying the length of one side by 4, so the perimeter of the square is 8 cm x 4 = 32 cm.

The perimeter of a rhombus, on the other hand, is calculated by multiplying the length of one side by 4 as well. However, a rhombus has equal side lengths but the opposite angles are not right angles like in a square. This means that the perimeter of the rhombus is larger than that of the square if they have the same side length.

Since the square and the rhombus both have a side length of 8 cm, their perimeter is not the same. Consequently, Bella’s statement is incorrect.
