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.
To find how many cm are in a ft, you have to use the method of unit rate:
so we know that 12 in. equals a ft. so,
1 ft
------
12 in.
and 2.25 cm equals an in. so,
1 in.
-------
2.54cm
then we put the rates together and get:
1ft 1 in.
---- X -------................we cancel out the in. units and get:
12 in. 2.54 cm
Solve and get 1 ft = 30.48 cm
