Answer:Step-by-step explanation:Let the width be w centimeters.

Then the length = w + 7.

The area A is found from the length multiplied by the width.

330 = w(w + 7) = w^2 + 7w.

Now we can rearrange this equation to form a quadratic, as follows:

The factorization of the quadratic is:

(w + 22)(w – 15) = 0

Therefore we find that:

width = 15 centimeters

length = 22 centimeters

Answer:length would be 47 or 47.1

Step-by-step explanation:its width is 7
