Shape A has a width of 0.5 square and a height of 1.5. This 0.5:1.5 ratio corresponds to the fireplace's 3:9 ratio because we can divide both values by 6.

Shape B has a width of 1 square and a height of 3. This 1:3 ratio corresponds to the fireplace's 3:9 ratio because we can divide both values by 3.

Shape C has a width of 2 square and a height of 6. This 2:6 ratio corresponds to the fireplace's 3:9 ratio because we can divide both values by 1.5.

Shape D has a width of 5 square and a height of 11. This 5:11 ratio does not correspond to the fireplace's 3:9 ratio.

Shape E has a width of 3 square and a height of 9. This 3:9 ratio is exactly the same as the fireplace's 3:9 ratio.

Shape F has a width of 4.5 square and a height of 13.5. This 4.5:13.5 ratio corresponds to the fireplace's 3:9 ratio because we can multiply both values by 1.5.
