Answer:

Part A) [tex]5\ in=15\ ft[/tex]

Part B) [tex]7\ in=21\ ft[/tex]

Step-by-step explanation:

we know that

The scale factor is [tex]\frac{1}{3}\frac{in}{ft}[/tex]

so

using proportion

Part A)

[tex]\frac{1}{3}\frac{in}{ft}=\frac{5}{x}\frac{in}{ft}\\ \\x=5*3\\ \\x=15\ ft[/tex]

therefore

[tex]5\ in=15\ ft[/tex]

Part B)

[tex]\frac{1}{3}\frac{in}{ft}=\frac{7}{x}\frac{in}{ft}\\ \\x=7*3\\ \\x=21\ ft[/tex]

therefore

[tex]7\ in=21\ ft[/tex]
