The difference is 12

first we should find out how much is the sum of length and width :
18 \div2 = 9
so we have to find 2 numbers with sum of 9
and least possible area.
the numbers will be 1,8 and the area is
1 \times 8 = 8

now let's find 2 numbers with sum of 9 and greatest possible area.
they are 4 and 5. the area is:
4 \times 5 = 20

the final answer will be the difference between these two areas
20 - 8 = 12

good luck
