This is the correct answer.
When adding mixed units, you can approach the problem in two ways.
3 feet 6 inches converts as:
3 feet x 12 inches/foot = 36 inches.
36 inches + 6 inches = 42 inches.
1 foot 8 inches converts to:
1 foot x 12 inches/foot = 12 inches.
12 inches + 8 inches = 20 inches.
Then
42 + 20 = 62 inches.
Convert this back to mixed units.
62 divided by 12 = 5 remainder 2,
which is 5 feet 2 inches.
Start with the inches because they are the smallest units.
Add 6 inches and 8 inches.
6 inches + 8 inches = 14 inches.
But 14 inches is more than 1 foot.
14 divided by 12 equals 1 with remainder 2,
which is 1 foot 2 inches.
Then move to the feet column.
3 feet + 1 foot + 1 foot (the 1 foot from the inches column) = 5 feet.
Therefore, the answer is 5 feet 2 inches.
