First, let us solve how many feet long a 36 inch board would be:
18 inches = 11/2 feet
36 inches x feet
x= 11/2 x 36 ÷ 18
x= 11
Therefore, a 36-inch board would be 11 feet long.
Next question!
18 inches = 11/2 feet
72 inches x feet
x= 11/2 x 72 ÷ 18
x= 22
Therefore, a 72-inch board would be 22 feet long.
Last question!
18 inches = 11/2 feet
144 inches x feet
x= 11/2 feet x 144 inches ÷ 18 inches
x= 44
Therefore, a 144-inch board would be 44 feet long.
Hope this helps!
