The perimeter of the shaded region is 39 ft.
The perimeter is the total length of all the sides of the shaded region. To find the perimeter, we need to add up the lengths of all the sides.
The perimeter of the shaded region is the sum of the lengths of all its sides.
Perimeter of a polygon = Sum of the lengths of all its sides
Perimeter of the shaded region = 14 ft + 6 ft + 15 ft + 4 ft
Perimeter of the shaded region = 39 ft
Therefore, the perimeter of the shaded region is 39 ft.
