Answer:
17.66m
Step-by-step explanation:
Let the area of the rectangular garden be L²
A = L²
19.5 = L²
L = √19.5
L = 4.416
Perimeter = 4L
Perimeter = 4(4.416)
Perimeter of the garden =17.66m
Hence the number of meters of fencing that are needed to go around the garden is 17.66m
0.000025
the difference between225-180=45
so the percentage= 45×100/100
=0.45%
as the instruction say=0.45%/180
=0.0045/180
=45/1800000
=0.000025
