Answer:
The shortest side is 4 feet.
Step-by-step explanation:
The perimeter is the border of a geometric figure and corresponds to the sum of the length of all its sides.
So the perimeter in the case of a triangle is the sum of its three sides:
L₁ + L₂ + L₃ =Perimeter
In this case, the perimeter is known and it is necessary to calculate the value of the shortest side. In that case it will be called L₁. So, you know:
- L₁= shortest side
- L₂=twice the length of the shortest side → L₂=2*L₁
- L₃=largest side (13 feet more than the shortest side) → L₃=L₁ + 13
- Perimeter= 29 feet
Replacing:
L₁ + 2*L₁ + L₁ + 13= 29
Solving:
(1+2+1)*L₁ + 13= 29
4*L₁ + 13=29
4*L₁ = 29-13
4*L₁ =16
L₁= 16÷4
L₁=4
The shortest side is 4 feet.
