29 yd. 2 ft. 11 in. + 55 yd. 1 ft. 10in. + 13 yd. 1 ft. 3 in.

So let's add the yards, 29+55+13, that's 97 yards.

let's add the feet, 2+1+1, that's 4 feet.

let's add the inches, 11+10+3, that's 24 inches.

h, 12 inches is 1 ft, so 24 inches is really 2 feet, so 4 + 2 is just 6 feet.

hmmm 3 ft is 1 yard, so 6 feet is really 2 yards.

97 + 2, 99 yards.
