Final answer:

The area of one of Rachel's earrings is 0.45 square inches. To find the total area for both earrings, we multiply by two, resulting in 0.9 square inches.

Step-by-step explanation:

To find the area of Rachels earrings, we first calculate the area of one earring using the formula A = 0.5 × base × height. Given the base is 3/5 inches and the height is 1 1/2 inches, we convert these to decimal form, which gives us 0.6 inches for the base and 1.5 inches for the height. Plugging these into the formula, the area of one earring is:

A = 0.5 × 0.6 × 1.5

A = 0.45 square inches for one earring.

To find the total area for both earrings, we simply double that amount:

Total area for both earrings = 2 × 0.45

Total area for both earrings = 0.9 square inches.

Answer:

9/10

Step-by-step explanation:

First, 1 1/2 as a improper fraction is 3/2

Second, 3/2 x 3/5 = 9/10

Third, you need to do 9/10 x 2 since there are two earings which equals 18/10.

Fourth, 18/10 divided by 2 = 9/10 which means that the area of both earrings is 9/10

Hope this helps!
