Answer:
One solution
Step-by-step explanation:
The given equation is;

Group similar terms;

Combine the similar terms to get;

Multiply both sides by -1 to obtain;

Therefore, there exist only one solution.
The perimeter of a rectangle is 2 times the length and 2 times the width. Since you got the perimeter (240), you can multiply 2 by the length (160) and subtract the perimeter (240) by it, giving you 80. This is 2 times the width. Divide that by 2 (divide 80 by 2) and you will get 40. The width is 40 feet.
