Find the perimeter of the triangle? what does 2 represent in the triangle?

6 + 5

Step-by-step explanation:

Since the triangle is isosceles then the 2 marked sides are congruent.

Using the rule of radicals

× ⇔

Thus perimeter (P) is the sum of the 3 sides

P = + 3 + + 3 +

  = 2 + 6 +

  = 2( ) + 6 +

  = 2 ( ×   ) + 6 +

  = 2(2 ) + 6 +

  = 4 + 6 +

  = 6 + 5

they are simplified
