Answer:
Option d is correct
4 meter
Step-by-step explanation:
Area of square is given by:
[tex]A = s^2[/tex]
where, s is the side of the square.
Let the length of each side of the original garden be x.
As per the statement:
A community group is planning the expansion of a square flower garden in a city park.
If each side of the original garden is increased by 9 meters.
New side of the garden become = x+ 9 meter.
It is also given that the new total area of the garden will be 169 square meters.
⇒A = 169 square meters
Using formula we have;
[tex](x+9)^2 = 169[/tex]
Taking square root both sides we have;
[tex]x+9 = 13[/tex]
Subtract 9 from both sides we have;
x = 4 meter
Therefore, the length of each side of the original garden is, 4 meters
