Answer:
C f=9
Step-by-step explanation:
isolate f on one side so you subtract 5 from both sides to get 3f=27 and then divide by 3 on each side to get f=9
7^-2= 1/7^2
= 1/14
= 0.071429
Solution :
For the bigger rectangle
Width of bigger rectangle = W
Length of bigger rectangle, L = 2W
For the smaller rectangle
Width , w = W+4
Length, l = L = 2W
Area, a =120 
Now we know,
Area = length x width






We get, either
(rejecting)
or 
∴ length of the bigger rectangle, 
= 2(6)
= 12 m
Length of the smaller rectangle, 
= 2(6)
= 12 m
Hence, the length of the two gardens is 12 m.
