Write an equation that relates the number of parallelograms in the figure (n) to the perimeter of the figure (P)

number 1. square has a 4 at each end and a 5 on the top of the square and one 5 on the bottom of the square

number 2. 2 squares attached side by side with a number 4 at each end and two 5s at the top and at the bottom of the squares

number 3. there are 3 squares attached side by side and a number 4 at each end and three 5's at the top and three 5's at the bottom

a. the equation for the perimeter is P= 10n + 8

b. the equation for the perimeter is P= 4n + 10

c. the equation for the perimeter is P= 4n + 5

D. the equation for the perimeter is P = 10n + 4
Please help me with this problem I am so confused
