The side length of an equilateral triangle is 16 cm. Calculate the length of a square with a perimeter

The side length of an equilateral triangle is 16 cm. Calculate the length of a square with a perimeter equal to the perimeter of this triangle.

When completing the task, we will need formulas to calculate the perimeter of a triangle and a square. In the general case, for a triangle, it is true P = a + b + c, where a, b, c are its sides. For an equilateral triangle, P = 3 * a is true. If a = 16 cm, then P = 3 * 16 = 48 cm. Now consider a square with its equal sides. The formula for its perimeter is P = 4 * a. We calculate the length of the side:

P = 4 * a
a = P: 4
a = 48: 4 = 12 cm

Answer: the length of the side of the square is 12 cm.
