Your answer is 406.8. You just multiply 10 by itself, the answer is 100, then you multiply 100 by 4.068.
0.25 = 3 ft
2/0.25 = 8....8 x 3 = 24 ft
3/0.25 = 12....12 x 3 = 36 ft
actual dimensions are : 24 ft by 36 ft
<span>Arrange the first row arbitrarily: 1 2 3 4.
Then there is only one option to begin the next row: 3.
The remaining row must be 4 1 2.
This leaves no options for beginning the third row (1 and 3 are in the same column, and 2 and 4 share the diagonal).</span>
