Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589

Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
The correct answer for this problem is A.
<u>Answer</u>:
B) The perimeter of the rectangle is 28 units.
E) The coordinates for the fourth vertex of the rectangle are (−5, −3).
<u>Step-by-step explanation</u>:
The length of the rectangle is 9 and width is 5.
- The perimeter is 2( 9 + 5 ) = 28 units
<em>as the upper one is right. Option A eliminated. </em>
- The coordinates for the fourth vertex of the rectangle are (−5, −3).
<em>as the upper one is right. option C and D will be eliminated.</em>
