Answer:
Mark needs 110 ft. fencing to surround all 4 gardens.
Step-by-step explanation:
Mark wants to fence 4 rectangular gardens. So we calculate the perimeter of the each garden by this formula 
P = 2(L) + 2(W)
Total Length of the garden = 
= 
Length = 18.5 feet
Total width of the garden = 
= 
Width = 9.0 feet
Perimeter of the garden = 18.5 + 9 = 27.5 feet
Mark wants to fence 4 garden 
Therefore, 27.5 × 4 = 110 feet.
Mark needs 110 ft. fencing to surround all 4 gardens.
