?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?

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.
