The solution would be like this for this specific problem:
A (table) = 4(24.26) * 6(24.26)
= 14,125.1424
A (quarter) = pi*r2
= 469.9
Total area (quarters) = 462.24 * 24
= 11,093.76
Area (not taken) = A (table) – Total Area (quarters)
= 14,125.1424 - 11,093.76
= 3,031.3824
= 3,031.38
The area of the table not covered in quarters is 3,031.38 mm2.
