Perimeter is the sum of the sides. An equilateral triangle has three sides of equal length. So the perimeter in this case would be 7.8mm x 3 = 23.4mm.
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
An equilateral triangle is going to have three equal sides. The perimeter is the sum of all three sides. To find the answer, divide the Perimeter (25.2 in.) by 3 (three sides) 25.2 in. / 3 = 8.4 in.
Perimeter = 3*25 = 75 cm
