Question

Jim has a floor plan for a porch that measures 5 inches long by 12 inches wide. The actual porch is 16 feet wide. What is the scale factor for this drawing? What is the porch’s actual length?

Answer 1

Answer:

Scale: 1:16

Porch length: $6 \frac{2}{3}$'

Step-by-step explanation:

In the floor plan the porch is 1 ft wide and in reality it is 16 ft wide, giving it a scale of 1:16.

The length of the porch can be found by

$\frac{12}{192}= \frac{5}{?}$

or by multiplying 5 by 16, then dividing by 12 to convert to feet.
