A triangle has a perimeter of 112 centimeters, each of the two longer sides of the triangle is three times as long as the shortest side. Find the length of each side of the triangle

Answer 1

short side ---- x
each of other sides (must be isosceles) ---- 3x

x + 3x + 3x = 112

I will let you finish it

Answer 2

short side = x
both long sides = 3x

x + 3x + 3x = 112
x + 6x = 112
7x = 112
divide both sides by 7
x = 16; 3x = 48
