The sum of the lengths of the four sides of a rectangle with sides measuring 7centimeters (cm) and 5centimeters (cm) is equal to the sum of the lengths of the four sides of a square. Find the length of one side of the square.
7 5 [OP_ADD] 2 [OP_MUL] 4 [OP_DIV]
var_a = 7
var_b = 5
var_c = var_a + var_b
var_d = 2
var_e = var_c * var_d
var_f = 4
var_g = var_e / var_f
print(int(var_g))
