Question

A conference will take place in a large hotel meeting room. The organizers of the conference have created a drawing. The scale indicates that 1/2 inch in the drawing represents 12 feet in the actual room. What is the actual length of the folding wall?

a) 2 in.
b) 4 in.
c) 6 in.
d) 2 1/3 in.

Answer 1

The actual length of the folding wall in the conference room is 24 inches.

Step-by-step explanation:

The scale of the drawing indicates that 1/2 inch on the drawing represents 12 feet in the actual room. To find the actual length of the folding wall, we need to set up a proportion using the scale factor:

1/2 inch (drawing) = 12 feet (actual room)

x inches (drawing) = ? (actual wall length)

Using cross multiplication, we can solve for x:

1/2 inch * ? = 12 feet * 1 inch

?/2 = 12

?

= 12 * 2

= 24 inches

Therefore, the actual length of the folding wall is 24 inches. So the correct answer is option a) 2 in.
