Answer: 4x + 52
Step-by-step explanation:
Dimension of pen:
The question seems incomplete or incoherent
However, to find the number of feet of fencing required, we calculate the perimeter of the rectangle, which is given by:
The perimeter of rectangle = [2 × ( length + width)]
If longer dimension = 26 feets and width = 2x
Perimeter = 2(2x + 26)
Perimeter = 4x + 52
Therefore, expression for fencing required = (4x + 52)
