if 18 inches is equal to 1 1/2 feet, how many feet long is a 36 inch board? A 72 inch board? A 144 inch board?

18 inches=  1 1/2 feet= 1.5 feet

18 inches = 1.5 feet

(1) Now we make a proportion to find feet for given inches

1.5 * 36 = 18*x

54 = 18 x (Divide by 18 on both sides)

x = 3

3 feet long is a 36 inch board

(2) 72 inch board

1.5 * 72 = 18*x

108 = 18 x (Divide by 18 on both sides)

x = 6

6 feet long is a 72 inch board

(3) 144 inch board

1.5 * 144 = 18*x

216 = 18 x (Divide by 18 on both sides)

x = 12

12 feet long is a 144 inch board

A 36-inch board would be 3 feet long, a 72-inch board would be 6 feet long, and a 144-inch board would be 12 feet long.

We have,

If 18 inches is equal to 1 1/2 feet, we can use this conversion factor to find the equivalent length in feet for different measurements.

For a 36-inch board:

We know that 18 inches is equal to 1 1/2 feet.

Therefore, 36 inches would be twice that length, which is 3 feet.

For a 72-inch board:

Again, using the conversion factor, we know that 18 inches is equal to 1 1/2 feet.

Therefore, 72 inches would be four times that length, which is 6 feet.

For a 144-inch board:

Using the same conversion factor, we can see that 18 inches is equal to 1 1/2 feet.

Therefore, 144 inches would be eight times that length, which is 12 feet.

Thus,

A 36-inch board would be 3 feet long, a 72-inch board would be 6 feet long, and a 144-inch board would be 12 feet long.
