Let: x = first consecutive integer (or first side of △) x + 1 = second consecutive integer (or second side of △) x + 2 = third consecutive integer (or third side of △)
The formula for a perimeter of △ is simply the addition of three sides (or length). Since the given perimeter is 114 cm, x + x+1 + x+2 = 114 3x + 3 = 114 3x = 114 - 3 3x = 111 x = 111 /3 = 37 cm The three sides are 37 cm, 38 cm, and 39 cm.
