if we add 6 feet 10 inches with 8 feet 9 inches we follow this route:
we add feet together and inches together
so we would have 14 feet and 19 inches, but we know that 1 feet is equal to 12 inches, so 19-12=7 inches left and we add this one 1 feet to our other part
so we will have 15feet 7inches B.
