Answer 1

Answer:

She went 7 km ...

the shortest distance ,

is the hypotenuse from the starting point to final point .

hypotenuse^2 = 3^2 +4^2

= 9+16

hypotenuse = √9+16

=√25

=5 km

Answer 2

Answer:

ans 5

Step-by-step explanation:

once u construct the figure u will notice that we have a right angle triangle with us so u can calculate the answer by pythagoras thm. so $3^{2}  +4^{2} =(side we want)^{2} \\9+16=25\\\sqrt{25} =5$
