Part A) $5\ in=15\ ft$

Part B) $7\ in=21\ ft$

Step-by-step explanation:

we know that

The scale factor is $\frac{1}{3}\frac{in}{ft}$

using proportion

Part A)

$\frac{1}{3}\frac{in}{ft}=\frac{5}{x}\frac{in}{ft}\\ \\x=5*3\\ \\x=15\ ft$

therefore

$5\ in=15\ ft$

Part B)

$\frac{1}{3}\frac{in}{ft}=\frac{7}{x}\frac{in}{ft}\\ \\x=7*3\\ \\x=21\ ft$

therefore

$7\ in=21\ ft$
