Best Answer

The figure is a triangle. That means it has 3 sides.

The triangle is "equilateral". That means all three sides have the same length.

One side is 5 cm. That means each of the other 2 sides is also 5 cm.

So the perimeter is (5 + 5 + 5) = 15 cm.

18 inches and it is an equilateral triangle

If the triangle is equilateral, you don't have a problem, but if not you have to measure the sides.

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.
