A school in Jaipur arranges students in a square formation for a march-past, so the number of rows equals the number of columns. When 11 extra students join, the total becomes 132. If the side of the square is x, which equation in standard form models this and what is x?

Question

Accepted Answer

11. x^2 + 11 = 132 gives x^2 - 121 = 0, so x^2 = 121 and x = 11 (taking the positive value).
