B; 25.65+13.23+6.35=45.23
To do this mentally just add the 2 decimals places together first (1.23). Then just add the whole numbers (44). Then add the 2 numbers together, 44+1.23=45.23
Scale factor is 2
30/15 = 2
20/10 = 2
Since one bus holds 36 students and 4 adults, 40 people are in one bus so...
40 (6)
=240
Total 240 people are going on the field trip.
Hope this helped you.
Have a great day!

Replace l with 110 and w with 120
P = 2(110) + 2(120)
P = 220 + 240
P = 460 feet
