Answer:
32 blocks
Step-by-step explanation:
distance between home (0,0) and mall (0,7) = 7
distance between mall (0,7) and movies (9,7) = 9
distance between movies (9,7) and store (9,0) = 7
distance between store (9,0) and home (0,0) = 9
7 + 9 + 7 + 9 = 32 blocks

Multiply both sides by 4
Take the square root of both sides
Subtract 5 from both sides

The total number of ways in which the 5 people can sit is: 5!=120: 5!=120

The number of ways in which d and e are not sitting together: 1120−24=96.
