Hi,

Note: A is area, s is length of the side and P is the Perimeter of each garden

A square garden plot measures 180 square feet. A+=+180

s%5B1%5D+=+sqrt%28180%29+=+sqrt%2836%2A5%29+=+6sqrt%285%29, P = 4%2As%5B1%5D=4%2A6sqrt%285%29=+24sqrt%285%29

A second square garden plot measures 405 square feet. A+=+405

s%5B2%5D+=+sqrt%28405%29+=+sqrt%2881%2A5%29+=+9sqrt%285%29, P =4%2As%5B2%5D=4%2A9sqrt%285%29=+36sqrt%285%29



 36sqrt%285%29+-+24sqrt%285%29+=+12sqrt%285%29
