The perimeter of the triangle shown to the right is 321 meters. Fin the length of each side.

first side: x meters

second side: 3x meters

third side: (4x-3) meters

Answer: First side is 40.5 meters. Second side is 121.5 meters. The third side is 159.

Step-by-step explanation:

x + 3x + 4x - 3 = 321

8x - 3 = 321

+3 + 3

8x = 324

x = 40.5

Second Side: 3 (40.5) = 121.5

Third side: 4 (40.5) - 3 = 159

Check: 159 + 121.5 + 40.5 = 321
