A square is made using four rods of equal length joined end to end.
The perimeter of this square is 72 cm. Three of these rods are now joined end to end to make an equilateral triangle.
What is the perimeter of this equilateral triangle?

Respuesta :

Answer: 54 cm

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Perimeter of a square = side length x4

Replacing with the values given:

72 = 4 s

Solving for s (side length)

72/4=s

s = 18 cm

Since the side length of the square is the length of each rod, and all the rods have the same length, to obtain the perimeter of the triangle we have to apply:

Perimeter of an equilateral triangle: 3 side length

P = 3 (18 ) = 54 cm
