Asquare has side length of 9 in. if the area is doubled, what happens to the side length?

The side length is multiplied by

Step-by-step explanation:

we know that

The area of the original square is equal to

If the area is doubled

then

The area of the larger square is

Remember that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the larger square

y ---> the area of the original square

so

we have

------> scale factor

therefore

The side length is multiplied by
