Question

Find the perimeter of an equilateral triangle
one
when one of its side is ,
-2x+5​

Answer 1

Answer:

The perimeter of any polygon is the sum of its side lengths. In an equilateral triangle, all of the sides are congruent (they are the same length). Thus, if an equilateral triangle has a side length of 2 , the perimeter is 2+2+2 because all of its sides are 2

Answer 2

Step-by-step explanation:

perimeter =sum of all sides

=-2x+5-2x+5-2x+5

=-6x+15
