Area of the garden is 360 sq ft, which is length times width of the garden.  In whole numbers  the factorization of 360 will be as shown below.

 

360= 1x2x2x2x3x3x5. we can now club these factors as follows as multiples of length and width:

 

360      = 1x360, this will give a perimeter = 2(1+360)= 722 ft

            = 2x180                                          = 2(2+180)= 364 ft

            = 3x120                                         = 2(3+120)= 246 ft

            = 4x90                                            = 2(4+90)  = 188 ft

            = 5x72                                            = 2(5+72)  = 154 ft

            = 6x60                                            = 2(6+60)  = 132 ft

            = 8x45                                            = 2(8+45)  = 106 ft

            = 9x40                                           = 2(9+40)  = 98 ft

            = 10x36                                          = 2(10+36)= 92ft     

            = 12x30                                          = 2(12+30)= 84ft

            = 15x24                                          = 2(15+24)= 78ft

            = 18x20                                          = 2(18+20)= 76 ft
