21 feet

Step-by-step explanation:

from mall she goes 9 feet south and then 12 feet west means. she is 9 + 12 = 21feet

Answer 2

Answer:

15

Step-by-step explanation:

Using pythogoras theorem, we can find thehypotenuse of the triangle,

${ac}^{2} = {ab}^{2} + {bc}^{2}$

${ac}^{2} = {9}^{2} + {12}^{2}$

${ac}^{2} = 81 + 144$

${ac}^{2} = 225$

$ac = \sqrt{225}$

$ac \: = 15$

Hence, The distance between the mall and her current position is 15 feet
