Answer:
{1 unit by (8x - 2) units}, or {2 units by (4x - 1) units}.
{(8x - 2) units by 1 unit}, or {(4x - 1) units by 2 units}.
Explanation:
The area of the rectangular hot tub is (8x - 2) sq. units.
If the dimensions of the hot tub cover are all whole numbers, then the possible dimensions of the hot tub cover will be {1 unit by (8x - 2) units}, or {2 units by (4x - 1) units}.
On the other way, the dimensions may be {(8x - 2) units by 1 unit}, or {(4x - 1) units by 2 units}. (Answer)
