The perimeter would be 18 cm.
Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
Perimeter = 4*4.5 = 18 feet
The isosceles triangle has a perimeter of: 14+14+9 = 37 feet
The perimeter would be 18 cm.
12 inches
8 feet x 3 sides = 24 foot perimeter.
24 feet (8 x 3)
Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
6 cm because well you tell the rest***************************************An equilateral triangle has three sides of equal length.Therefore: if the length of one side measures 18cm then 18 x 3 = 54 centimetre is the perimeter.
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.
Perimeter = 4*4.5 = 18 feet
The perimeter (sum of the lengths of the sides) would be 3 x 2 cm = 6 cm *This is actually seeing if one knows the definition of "equilateral triangle", i.e. that all three sides have the same length.
The isosceles triangle has a perimeter of: 14+14+9 = 37 feet
you must multiply it by three
