Question

The measure of each side of a triangle is 2x+5. Find the perimeter of the triangle

 

Answer 1

Perimeter= addition of all side

 

perimeter of triangle = addition of  3 sides of triangle

 

Given that

The measure of each side of a triangle is 2x+5                          

 

perimeter =(2x+5)+(2x+5)+(2x+5)

 

              =2x+5+2x+5+2x+5

 

               =2x+2x+2x+5+5+5

 

                =6x+15

 

 

Answer 2

Lacking any other information, the perimeter is the sum of the sides, or

Perimeter=3(2x+5)

Perimeter=6x+15
