Given information:
Length of one side of an equilateral triangle = 126 cm

To find:
Perimeter of the triangle

Solution:
An equilateral triangle has all three sides of equal length. Therefore, to find the perimeter of the triangle, we need to multiply the length of one side by 3.

Let's calculate the perimeter using the given information:

Perimeter of the triangle = 3 * Length of one side

Substituting the given length of one side as 126 cm:

Perimeter = 3 * 126 cm

Calculating the product:

Perimeter = 378 cm

Therefore, the perimeter of the equilateral triangle is 378 cm.

Hence, the correct answer is option D) 378 cm.
