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
