Question

The parks and recreation organization has decided to add a sidewalk around a big oak tree in the park.
They are hoping that this will decrease the amount of foot traffic in front of the tree.
A diagram showing the old and new sidewalks is shown.

About how many additional feet will a person travel if they walk along the new path?
A. 18 feet
B. 24 feet
C. 45 feet
D. 51 feet

Answer 1

c^2 = a^2+b^2
c^2 = 24^2+48^2
c= 53.66

24 + 48 = 72
72- 53.66 = 18.33 =18
