# Create list areasareas = [11.25, 18.0, 20.0, 10.75, 9.50]# Print out the index of the element 20.0print(areas.index(20.0))# Print out how often 14.5 appears in areasprint(areas.count(14.5))

# Create list areasareas = [11.25, 18.0, 20.0, 10.75, 9.50]# Use append twice to add poolhouse and garage sizeareas.append(24.5)areas.append(15.45)# Print out areasprint(areas)# Reverse the orders of the elements in areasareas.reverse()# Print out areasprint(areas)
