Answer:
The longest possible values of the other two sides are 7 ft and 14 ft
Step-by-step explanation:
Let one side of the triangle be x and the other, 2x
Perimeter of a triangle = sum of all sides; i.e x+2x+33
Therefore, x+2x+12=33
Solve for x;
3x=33-12
3x=21
Divide both sides by 3; x=21/3
therefore, x=7 and
2x= (2*7) = 14
The longest possible values of the other two sides are 7 ft and 14 ft
