You would multiply 8 x 4 to get the area which would give you 32.
Answer:
b² - 121
Step-by-step explanation:
(b +11)(b - 11)
b² - 11b + 11b - 121
b² - 121
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.
