It is $88$ inches or $7$ feet and $4$ inches.

Explanation:

As each feet has $12$ inches, $4$ feet have $4×12=48$ inches. Hence $4$ feet and $7$ inches are $48+7=55$ inches

and adding $33$ inches to $4$ feet and $7$ inches is $33+55=88$ inches.

Now as $12$ inches equal to one foot and $88=7×12+4$ , we can also write $88$ inches as $7$ feet and $4$ inches.

$7 " feet " and 4 " inches "$

Explanation:

You cannot add number which are in different units, so something has to be converted.

Let's convert $" " 33$ inches to feet and inches and then add.

$1 " foot " = 12 " inches"$

$33$ inches = (24 + 9 ) inches = 2 feet and 9 inches (24+9)
