If the shortest side of the triangle is x, the other one measures 2x
the third is 30 feet more than shortest, so it's lenght is (x + 30)
and the sum of all three sides (perimeter) is 182
So we can write:
x + 2x + (x + 30) = 182
Soving for x:
x + 2x + x + 30 = 182
4x = 182 - 30 = 152
4x = 152
x = 152/4 = 38
Answer: 38 feet
The length of the shortest side is 38 feet
The shortest is 38
The second one is 2 (38) = 76
the third one is x + 30 = 38+30 = 68
The second is 76 feet
and the third is 68 feet
