The triangle is scalene and the largest side measures 69 inches.
Let x be the first, smallest, side. Then x+2 would represent the second smallest side and x+4 would represent the largest side. Since the perimeter is 201,
x+(x+2)+(x+4) = 201
Combining like terms, we have
3x+6 = 201
Subtract 6 from both sides:
3x = 195
Divide both sides by 3:
x = 65
This means the next side is 65+2 = 67 and the largest side is 65+4 = 69.
The three sides are all different which makes the triangle scalene.
The largest side is 69 inches.
