The correct answer is option d.) No.
To determine if the two flags are similar, we can analyze their proportions. Let's denote the green flag's height as
, the green flag's length as
, the blue flag's height as
, and the blue flag's length as
.
For the green flag:
![\[ h_g = 1.5 \, \text{ft}, \quad l_g = 2.5 \, \text{ft} \]](https://img.qammunity.org/2022/formulas/mathematics/high-school/dy5mnxnujtpmtvap2pr25p3g7es2k71pto.png)
For the blue flag:
![\[ h_b = 10 \, \text{inches}, \quad l_b = 18 \, \text{inches} \]](https://img.qammunity.org/2022/formulas/mathematics/high-school/807jfzna5iu43p6pwmuq2k0n9kz32y8jw7.png)
Now, let's convert all measurements to the same units. Since 1 foot equals 12 inches, we have:
![\[ h_g = 1.5 * 12 = 18 \, \text{inches}, \quad l_g = 2.5 * 12 = 30 \, \text{inches} \]](https://img.qammunity.org/2022/formulas/mathematics/high-school/zih5entrw5tae31gm7r5voqhdunusko5f0.png)
Now we can compare the ratios of corresponding sides:
![\[ (h_g)/(h_b) = (18)/(10) = (9)/(5) \]](https://img.qammunity.org/2022/formulas/mathematics/high-school/z6dl1llqvvkpwn7okoxum4j030fz6z62xq.png)
![\[ (l_g)/(l_b) = (30)/(18) = (5)/(3) \]](https://img.qammunity.org/2022/formulas/mathematics/high-school/bojue7tb3pfbmrkjhan94lsfm0zp07zb32.png)
The ratios are not equal, indicating that the flags are not similar.
Conclusion:
d. No
