Numbers (of objects) that can be arranged into a square array are called square numbers. Not a square number: Square arrays must be full if we are to count the number as a square number. Here are 12 pennies arranged in a square, but not a full square array. The number 12 is not a square number.
Since 13 is not a square number there is no exact real answer, but you can find an approximate value using the following (Newton-Raphson) iteration formula: xn+1=x n - (x2n -13)/(2xn). Using this formula the square root of 13 can be stated as 3.605551275 to 10 s.f. after 3 iterations starting from 3.5.
