Answer:

4 1/2 ft

Step-by-step explanation:

1 yard = 36 inches

2 yards = 2 × 1 yard = 2 × 36 inches = 72 inches

The board started with a length of 72 inches.

He used 18 inches.

72 in. - 18 in. = 54 in.

He has 54 in. left.

Now we convert 54 in. to ft.

1 ft = 12 in.

54 in. × (1 ft)/(12 in.) = 4.5 ft = 4 1/2 ft
