Explanation:

Answer 2

Given that the floor plan for a particular room calls for 17 boards, each 7 feet 7 inches in length.

There are 12 inches in 1 foot, thus 7 feet 7 inches is equivalent to
`7 (7)/(12) \, feet`.

The total length of all the boards is given by


`7 (7)/(12) * 17= (91)/(12) *17 \\ \\ = (1547)/(12) =128 (11)/(12)`

Therefore, the total length of all the boards is 128 feet 11 inches.
