10 ) perimeter = 2(l+b)
218/15 = 2(14/3 + b)
218/15 = 28 / 3 + 2b
218 / 15 - 28 / 3 = 2b
218/15 - 140/15 = 2b
78/15 = 2b
b = 78/ 15 * 1/ 2
b = 36 / 15 = 12 / 5 ans .
hope it helps you!
9) passengers = 144
passengers in lower deck = 5/12
now, passengers= 144 * 5/ 12=60 passengers
passengers in upper deck = 144 - 60 = 84 ans.
8) length of road = 540 m.
repaired road = 540 *2/3 =360m
unrepaired road = 540 - 360
= 180 m ans.
