Question

On an architects blue print 1 inch corresponds to 9 feet find the length of a wall represented by a line 1 1/3 inches long on the blueprint round to the nearest 10th if necessary

Answer 1

The actual length of the wall is;

`12\text{ feet}`

Step-by-step explanation:

Given that On an architect's blueprint 1 inch corresponds to 9 feet.

The ratio is;

`r=\frac{9ft}{1\text{ inch}}`

So, for 1 1/3 inches long wall on the blueprint, the actual length will be;

`\begin{gathered} l=1(1)/(3)\text{inches }*\frac{9ft}{1\text{ inch}} \\ l=(4)/(3)\text{ inch }*\frac{9ft}{1\text{ inch}} \\ l=12\text{ feet} \end{gathered}`

Therefore, the actual length of the wall is;

`12\text{ feet}`
