Jawapan:

# = warna (biru) (sqrt10 #

Penjelasan:

# (2,3) = warna (biru) ((x_1, y_1) #

# (3,0) = warna (biru) ((x_2, y_2) #

Jarak dikira mengikut formula:

jarak # = sqrt ((x_2-x_1) ^ 2 + (y_2-y_1) ^ 2 #

# = sqrt ((3-2) ^ 2 + (0-3) ^ 2 #

# = sqrt ((1) ^ 2 + (-3) ^ 2 #

# = sqrt ((1 + 9) #

# = warna (biru) (sqrt10 #
