In equilateral triangle ABC, AB=3x and BC= 2x=12. Find the numerical value of the perimeter of ABC.

• math -

x=6
so i believe the answer would be
18+12+12 which equals 42
im not for sure though but that's how i think you would do it

• math -

If BC = 12, then each side = 12 and the
perimeter would be 3 * 12 = 36. please

• math -

I think Troy has a typo
and it should say
BC = 2x+12

so 3x = 2x+12
x = 12

any other interpretation will lead to a contradiction, since the triangle is equilateral.

perimeter = 36
