Question

If all three sides of a triangle have length x, what is the perimeter of the triangle?

A. x/3
B. x + x + x + x
C. 3x
D. 3 + x

Answer 1

It’s definitely 3x because if it has 3 sides “x+x+x” you shorten it up to 3x.

Answer 2

C) 3x

Explanation:

Perimeter can be defined as side a + side b + side c,

since all sides are x we have

x + x + x = 3x
