Answer: See explanation
Explanation:
Area of a rectangle = length × width
From the question, we are informed that the length of a rectangle is 8 feet, and its area is less than 168 square feet.
Therefore, the width will be calculated thus:
Length × Width < 168
8 × Width < 168
8W < 168
W < 168/8
W < 21
The width is less than 21 feet
