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.
