Answer 2

Answer:

12 ft 2 in.

Step-by-step explanation:

Conversion: 1 ft = 12 in.

Add the lengths of the boards.

4 ft 10 in. + 2 ft 11 in. + 4 ft 5 in. =

= 4 ft + 2 ft + 4 ft + 10 in. + 11 in. + 5 in.

= 10 ft + 26 in.

= 10 ft + 24 in. + 2 in.

Since 1 ft = 12 in., then 24 in. = 2 ft.

= 10 ft + 2 ft  + 2 in.
