The perimeter of the triangle is 12 cm. This is 12 cm less than the perimeter of the square.

The perimeter of the triangle is 12 cm. This is 12 cm less than the perimeter of the square. How long is the side of the square?

The first step is to calculate the perimeter of the square:
1) 12 cm + 12 cm = 24 cm perimeter of the square.
The perimeter of a square is calculated as the sum of the lengths of its sides. P = 4 * a. The length of the side of the square can be calculated by the formula a = P / 4.
2) 24cm: 4 = 6cm side length of the square.
Answer: the length of the side of the square is 6 centimeters.
