The expression to represent the perimeter of the triangle is 3.6x - 24

The value of x when perimeter of the triangle equals 12 is 10.

An equilateral triangle has all its sides equal to each other.

The perimeter of a figure is the sum of all its sides. A triangle has three sides.

Therefore,

perimeter = 1.2x- 8 + 1.2x - 8 + 1.2x - 8

perimeter = 3.6x - 24

If the triangle has a perimeter of 12 the value of x can be found below:

12 = 3.6x - 24

12 + 24 = 3.6x

3.6x = 36

divide both sides by 3.6

3.6x / 3.6 = 36 / 3.6

x = 10
