Answer:
110 feet
Step-by-step explanation:
Given that,
Length of the rectangular garden = 9 1/4 feet = 37/4 feet
Width of the rectangular garden = 4 1/2 feet = 9/4 feet
We need to find the total length of fencing Mark needs to surround all 4 gardens.
The length for 1 garden = perimeter of the garden
The length for 4 garden = 4×perimeter of the garden
= 4×2(l+b)
Hence, 110 feet is the total length of the fencing Mark needs to surround all 4 gardens.
