Question

the side length of a square can be expressed as 2x+3. If the area of the square is 121 square meters, what is the value of x?

Answer 1

Answer:

x=4

Step-by-step explanation:

(2x+3)^2=121

2x+3=square root of 121

2x+3=11

2x=11-3

2x=8

x=4

(in a square all sides are equal therefore area =length ×width where length and width=2x+3)
