If each side is 12 cm then its perimeter is 6 times 12 = 72 cm
7 X 12 = 84 this is the perimeter
48 meters.

12
well its lxw=12
Each side will work out as 12/4 = 3 inches
The length of each side of the triangle is 12 miles.
You could have a 3,4,5 right triangle (perimeter=12), or an equilateral triangle with each side = 4, then a square with each side = 3, a rectangle with length=5 & width=1, a pentagon with each side= 2.4, a hexagon with each side = 2, a decagon (10 sides) with each side= 1.2, a dodecagon (12 sides) with each side = 1. You could go on and on.
In a square, all four sides are of equal length. Divide the perimeter by four to find the length of each side: 12 ÷ 4 = 3 ft
12 cm
The perimeter of the equilateral triangle is 3 times 4 = 12 cm
