Find the area of an equilateral triangle if its perimeter is 18 ft
Given a perimeter of 18 units, the resulting altitude is 5.2 (5.19615) units.
18
x+4+x+2+x = 24 3x+6 = 24 3x = 24-6 3x = 18 x = 6 longest side = 10 inches
3 cm x 6 sides = 18 cm perimeter
The perimeter would be 18 cm.
6 inches
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.

6 and 3/8
18 inches and it is an equilateral triangle
Area equals 15.59

Let's express the side length of an equilateral triangle, a, in term of the height h.a = (1/3)(h)(sq.root of 3)The perimeter equals to 3a. So we have:3a = 3[(1/3)(h)(sq.root of 3)] = (h)(sq.root of 3)] = 18(sq.root of 3)
perimeer of the triangle = sum of all the sides = 18 +18+11= 47 cm hence perimeter is 47 cm
It depends. What shape is it? And is it equilateral or not?
