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?
1 answer:
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)
