If the original data to send is 10011001 11100010 00100100 10000100. How would it be possible to detect error using two dimensional error detecting technique?

Two-dimensional Parity check
Parity check bits are calculated for each row, which is equivalent to a simple parity check bit. Parity check bits are also calculated for all columns, then both are sent along with the data. At the receiving end, these are compared with the parity bits calculated on the received data.

also,
10011001 + 11100010 + 00100100 + 10000100 = 1000100011
Since the result consists of 10 bits, so extra 2 bits
00100011 + 10 = 00100101 (8 bits)
1’s complement =11011010
checksum value = 11011010
Sum of all segments + Checksum value = 11111111
Complemented value = 00000000
the result is 0, the receiver assumes no error occurred in the data
