side of first garden =sqrt(125)=11.18 ft

Fencing required =4s=4*11.15 =44.72ft

side of second garden =sqrt(405)=20.12 ft

Fencing required =4s=4*20.12=80.48 ft

Extra fencing required for second garden =80.48-20.12

=60.36 ft.

but that's not one of the answers.... what am I doing wrong

$$\sqrt{405}*4-\sqrt{125}*4=16 \sqrt{5} $$
