The scale drawing of a porch is 8 inches wide by 12 inches long. If the actual porch is 12 feet wide, what is the length of the porch?

The actual length of the porch is 18 feet.

Explanation:

Scale =

So that considering the width of the drawing and actual porch,

1 foot = 12 inches

12 feet = 12 x 12 inches

           = 144 inches

scale =

         =

Given that the length of the porch drawn is 12 inches, let the actual length of the porch be represented by x. Then the actual length can be determined by;

scale =

=

x = 12 x 18

  = 216

x = 216 inches

But,

1 foot = 12 inches

216 inches = 18 feet

The actual length of the porch is 18 feet.
