Final answer:
To find the value of x, we can use the formula for the area of a square and solve the equation algebraically. The value of x is 9.
Step-by-step explanation:
To find the value of x, we can use the formula for the area of a square, which is side length x side length. In this case, the area is given as 121 square meters, so we can set up the equation as follows: (2x+3)(2x+3) = 121. To solve for x, we can expand the equation, combine like terms, and then solve using algebraic methods. The value of x is 9.
