In this case, all letters are unique.
Start by holding the first letter:
E - XAM
E - XMA
E - MAX
E - MXA
E - AXM
E - AMX

Step-by-step explanation:
Your total backyard is 18ft * 9ft = 162 ft^2
Your patio is 5ft * 8ft = 40 ft^2
Your Garden is 4ft * 7ft = 28 ft^2
Your walkway is 3ft * 9ft = 27 ft^2
Add all those areas together you have 95 ft^2
95 of 162 = 58.61%
