Consider this option:

if Jackie want to make the scale 3 times bigger, it means that new area of the map is 3 times bigger: new_area=3*init_area.

If the init_area is increased by 3 times, it means that the init_length (the scale) is increased by √3≈1.71 times.

If initial scale is 1:12, the new scale is 1:12*√3≈1:20.7846
