b) 0.1
Explanation:
a)
The width must be able to go up to 35.
Each square is 5 units wide.
35/5 = 7
The grid must be at least 7 squares wide.
b)
The highest y-coordinate is 1.7.
The highest point on the grid should be 2.
There are 20 vertical squares on the grid.
2/20 = 0.1
Each vertical square should be 0.1
A = 0.1
