Question

designing an orphanage
scale drawings
determine the length of the room using proportions. what is the actual length for the bedroom?
on a set of architectural drawings for a home, the scale is 1 inch for every 3 feet. the length of the bedroom wall in the drawing is 4 inches.
0 feet

Explanation:

Step1: Set up the proportion

Let \(x\) be the actual length. The proportion is \(\frac{1\ \text{inch}}{3\ \text{feet}}=\frac{4\ \text{inches}}{x}\).

Step2: Cross - multiply

\(1\times x = 3\times4\).

Step3: Solve for \(x\)

\(x = 12\).

Answer:

12
