qwelly [4]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

The longest side measures :

  • 27\:  \: cm

<h3>\large \boxed{ \mathfrak{Explanation}}</h3>

Perimeter of a triangle is equal to sum of measures of its all three sides, that is :

  • x + x + 8 + x + 12

and according to the question, the perimeter of the triangle is = 65 cm

so, let's equate both the expressions to find value of x :

  • x + x + 8 + x + 12 = 65
  • 3x + 20 = 65
  • 3x = 65 - 20
  • 3x = 45
  • x = 45 \div 3
  • x = 15

The longest side of the Triangle is :

  • x + 12
  • 15 + 12
  • 27 \:  \: cm
