Answer:
Perimeter = 40 inches
Step-by-step explanation:
Length = 16 inches
Width = 25% of length (16)
           = 25% of 16
25% = 1/4
Width = 1/4 x 16
           = 4 inches
Length = 16 inches
Width = 4 inches
Perimeter of a rectangle = length + length + width + width:
                                          = 16 + 16 + 4 + 4
                                          = 32 + 8
                                          = 40
PERIMETER = 40 inches
So glad I could help :)
