Answer:

(a)\ k_2 = 1in:3ft

(b)\ Scale\ width =\frac{16}{3}\ in

Step-by-step explanation:

Given

k_1 = 1in : 2ft --- Initial scale factor

Blueprint: 12in\ by\ 8in --- Missing from the question

Solving (a): The new scale factor.

Convert the initial blueprint to actual measurement using the initial scale factor, we have:

Length = 12 * 2ft = 24ft

Width = 8 * 2ft = 16ft

From the question, we understand the new scale factor represents the width as 8in.

The scale factor (k2) is then calculated as:

k_2 = \frac{Scale\ length}{Actual\ length}

k_2 = \frac{8in}{24ft}

Simplify

k_2 = \frac{1in}{3ft}

Represent as fraction

k_2 = 1in:3ft

The above is the new scale factor

 Solving (b): The new width

Using the scale factor above we have:

k_2 = \frac{Scale\ width}{Actual\ width}

\frac{1in}{3ft} = \frac{Scale\ width}{16ft}

The 16 is gotten from:

Width = 8 * 2ft = 16ft

So, we have:

Scale\ width = 16ft * \frac{1in}{3ft}

Scale\ width = 16 * \frac{1in}{3}

Scale\ width =\frac{16\ in}{3}

Scale\ width =\frac{16}{3}\ in

<em>Hence, the scale width of the blueprint is: 16/3 inches</em>
