A rectangle and a square have the same area, and the sides of the rectangle are 9 centimeters (cm) and 16 centimeters (cm), respectively. In this case, find the length of one side of the square in centimeters (cm).
9 16 [OP_MUL] 1/2 [OP_POW]
var_a = 9
var_b = 16
var_c = var_a * var_b
var_d = 0.5
var_e = var_c ** var_d
print(int(var_e))
