Answer:
total length of fencing: 110 feet
Find the perimeter of one garden:
[tex]\sf 2 ( length + width )[/tex]
[tex]\sf 2 ( 9\frac{1}{4} + 4\frac{1}{2} )[/tex]
[tex]\sf 2 ( \frac{37}{4} + \frac{9}{2} )[/tex]
[tex]\sf 2 ( \frac{37}{4} + \frac{18}{4} )[/tex]
[tex]\sf 2 ( \frac{37+18}{4} )[/tex]
[tex]\sf 2 ( \frac{55}{4} )[/tex]
[tex]\sf ( \frac{55}{2} )[/tex]
[tex]\sf 27.5 \ feet[/tex]
Then 4 rectangular gardens:
[tex]\sf 4 (27.5) \ feet[/tex]
[tex]\sf 110 \ feet[/tex]
