Question

A board 5 feet 2 inches long board 3 ft 7 inches long what's the length remaining

Answer 1

Convert to inches. 5 ft 2 in is equal to 62 inches, and 3 ft 7 in is equal to 43. 62-43=19 convert back to feet and inches if needed. You should end up with 1 ft 7 in.

Answer 2

1 ft 7 inches i presume.

5ft 2 inches - 3 ft 7 inches = 1 ft 7 inches

If i get this wrong its because i had a brainfart.
