The perimeters of an equilateral triangle and a square are equal. If one side of triangle is 5 meters long, find the length of the side of the square

If one side of the square is as long as the the diameter of a circle, find the ratio of the perimeter of the square to the circumference of the circle

Mr F says: Solve 15 = 4x. (You know where the 15 has come from, right?)

If one side of the square is as long as the the diameter of a circle, find the ratio of the perimeter of the square to the circumference of the circle

Mr F says: 4x : pi x => 4 : pi

In both cases x is the length of one side of the square.
