Sagot :
Answer:
x = 4 meters
Explanation:
The area of the square is 121 sq meters. 121 is 11 squared. The shape is a square so the side must be 11 meters.
2x + 3 = 11
2x = 8
x = 4
A longer, more complicated algebrai-ish way if to solve the equation:
(2x + 3)^2 = 121
which would give the same answer. But the shape was a square, so use that fact for a simple and elegant solution.
