A square garden plot measures 125 square feet. a second square garden plot measures 405 square feet. how many more feet of fence will the second garden plot require over that required for the first garden plot.

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.
