Answer:

The value of x is 4.

Step-by-step explanation:

Given that,

The side length of a square a = 2x+3

Area of the square = 121

We know that,

The formula of area of square is

[tex]A= a^2[/tex]

We substitute the value into formula

[tex]121=(2x+3)^2[/tex]

On taking square both sides

[tex]\sqrt{121}=2x+3[/tex]

[tex]11=2x+3[/tex]

[tex]2x=11-3[/tex]

[tex]x = \dfrac{8}{2}[/tex]

[tex]x = 4[/tex]

Hence, The value of x is 4.
