If photo is not clear, refer:
I assumed that the given question says,
Square of side = 20m.50cm
Using the data,
Perimeter of Square = 4a
We have, a = 20.5 cm (20m.50cm is nothing but 20.5m; considering m)
Now,
4 x a
4 ( 20.5 ) m
82 m
Now cost per meter: $8
So,
Total Cost = $8 x 82 m
= $656
Hence the total cost of fencing is $656
