Answer:
So longest side is 6 units more then the shorter side
The third side is twice the length of the shortest side
The perimeter (all 3 sides added up) is 25.
What’s the 3 sides of the triangle.
So lets make variables.
Let’s make the shortest side of the triangle “s”.
The longest side is 6 units more then the shorter side so
S + 6 is the longest side.
The third side is twice the length of the shortest side so
2S is the third side
S of course is already the shortest side now solve.
s + 6 + 2s + s = 25 <— This is your equation
Now solve
4s + 6 =25
4s = 19
s = 4.75
The shortest side is 4.75
The longest side is 4.75 + 6 which is 10.75
The third side is 2 times the shortest side which is 4.75 * 2 which is 9.50
