The perimeter of a triangle is 84 mperiod the longest side of the triangle is 7 m less than twice the length of the shortest side, x. the middle side is 7 m longer than the shorter side. what is the length of each side of the triangle

short side =x

medium side = x+7

longest side = 2x-7

write equation:

x+x+7+2x-7=84

4x=84

divide each side by 4

x=21 short side

x+7=21+7=28 medium side

2x-7=2(21)-7=42-7=35 longest side
