21, 23 ...
(19, both numbers would be odd)
Do you know what odd and even means?
If you mean, "What is the largest number of digits possible in the product of two 2-digit numbers" then 99 * 99 = 9801, or 4 digits. Anything down to 59 * 17 = 1003 will have 4 digits.
67/72 of them.
from 3 digits (10x10) to 4 digits (99X99)

74 cm2 or 74 square cm. Although 13 * 5.7 is 74.1, the two numbers are given to only two significant digits and it would not be correct to report their product to any greater degree of accuracy.
By the definition of place values representation of numbers, there cannot be any.

If you mean, "What is the largest number of digits possible in the product of two 2-digit numbers" then 99 * 99 = 9801, or 4 digits. Anything down to 59 * 17 = 1003 will have 4 digits.
67/72 of them.
Because in our system of numbers 100,000 is greater than 99,999.
from 3 digits (10x10) to 4 digits (99X99)
You had me until "product." The product of 4 digits can't be prime.
The 2-digit number must be 20, because it is the only 2-digit number whose sum of its two even digits, 2 + 0 = 2, is greater than the product of its two even digits, 2 x 0 = 0. Moreover, 20 is a product of the two consecutive integers 4 and 5.
Zero.
There are two numbers that satisfy the criteria. 38 and 83
0 and 9 or, 0 and anything really.
