4mm
The sides of the new garden can be represented by x+9. x is the original size and 9 is the added 9mm. Multiply the sides to get (x+9)(x+9) or

this will equal the area. Create an equation to solve for the unknown original length.

Take the square root of both sides
13=x+9
Subtract both sides by 9
4=x The original side was 4mm long
456. none of the other options make sense
The answer is -25
All you have to do is add -6-9 which equals -25 because “same signs add(+) and keep” “different signs subtract(-)” but “add” means positive number and “subtract” means negative number. Since they are different signs a (+) and a (-) you subtract it.
Hope this helps!
