The expression can be used to show the length of one side of the triangle is 4x+6.
Given
An equilateral triangle has a perimeter of 12 x + 18 units.
What is the perimeter of an equilateral triangle?
The perimeter of the Equilateral Triangle is simply the sum of its three sides which are equal in length. Perimeter is denoted by the P symbol.
[tex]\rm Perimeter= 3 \times S[/tex]
Therefore,
The expression that can be used to show the length of one side of the triangle is;
[tex]\rm Perimeter = 12x+18\\\\Perimeter = 3(4x+6)[/tex]
Hence, the expression can be used to show the length of one side of the triangle is 4x+6.
