Final answer:
The perimeter of an equilateral triangle with sides each measuring 4 meters is 12 meters.
Step-by-step explanation:
The student is asking for the perimeter of a triangle with congruent side lengths of 4 meters. To find the perimeter of any polygon, including a triangle, one needs to sum the lengths of all its sides. Since the triangle in question has three sides of equal length (congruent), it is an equilateral triangle, and the perimeter (P) can be calculated as:
P = side length × number of sides
P = 4 meters × 3
P = 12 meters
Thus, the perimeter of the triangle is 12 meters.
