Okay, so the first thing you need to do is find the difference.
64.19 - 59.99 = 4.20
So the percentage is determined by dividing that difference by the cost of the item originally:
4.20 / 59.99 = about .07
Next, you change this number to a percentage by moving the decimal to the right two spaces, so that would be 7%.
Therefore, the sales tax in the area is 7%.
Let x be the side of your square. Use Pythagoras to find the side in the right triangle formed with 2 sides and the diagonals:
x² + x² = 34²
2x² = 34² = 1126
x² = 1126/2 = 578
and x =√578 = 17√2 ≈ 24 ft
H will need 24 x 4 = 96 ft
