An equilateral triangle has three sides of equal length. Therefore, the perimeter of the triangle is 3 times the length of one side. Perimeter = 3(2.4 ft) = 7.2 ft. An equilateral triangle has three equal sides, so the perimeter is just three times the length of one side. Thus, the perimeter is 3 x 2.4 ft = 7.2 ft. Therefore, the answer is choice C).
