3. Im pretty sure hold on 14^ =69 x-9
Answer:

Step-by-step explanation:
First find the area of the rectangle: 10 * 40 = 400
Now, since the square has the same area, we'll find the side lengths of the square by just finding the square root of 400 which is 20. You can do this with a calculator. So the side length of any side on the square is 20.
