Let the number be x.

L = length = 3x + 5

W = width = 2x - 3

A = LW = (3x + 5)(2x - 3)

Without additional information, a final answer cannot be given, so at best you have area in terms of x.

length of a rectangle is five more than three times a number: L = 5 + 3x = 3x + 5

width is 3 less than twice the number: W = -3 + 2x = 2x - 3

find the area: A = LW = (3x + 5)(2x - 3)

The words of the problem statement were translated correctly into algebra, and the formula for area of a rectangle was applied correctly. There is nothing wrong with this solution.
