The perimeter of the triangle is [tex]5.5x+9[/tex]
If the sides of a triangle are[tex]s_1 ,s_2 \ and \ s_3[/tex]. The formula for calculating the perimeter of the triangle is expressed as:
[tex]P=s_1+s_2+s_3[/tex]
Given the sides of the triangle expressed as:
[tex]s_1=0.3x +24\\s_2=5x\\s_3=0.2x-15[/tex]
Substituting the given sides into the formula as shown:
[tex]P=0.3x+24+5x+0.2x-15\\P=0.3x+5x+0.2x+24-15\\P=5.5x+9[/tex]
Hence the perimeter of the triangle is [tex]5.5x+9[/tex]
