To determine the true statements about the gardens, we need to convert the measurements of each side length from inches to feet according to the given scales.
1. **Magazine Scale: 1 inch = 3.5 feet**
- Length A (8 inches):
\( 8 \text{ inches} \times 3.5 \text{ feet/inch} = 28 \text{ feet} \)
- Length B (5 inches):
\( 5 \text{ inches} \times 3.5 \text{ feet/inch} = 17.5 \text{ feet} \)
- Length C (10 inches):
\( 10 \text{ inches} \times 3.5 \text{ feet/inch} = 35 \text{ feet} \)
2. **Imogen's Scale: 2 inches = 6 feet**
- To convert inches to feet, we can use the conversion of 2 inches to 6 feet. This means that 1 inch = 3 feet.
- Length A (8 inches):
\( 8 \text{ inches} \times 3 \text{ feet/inch} = 24 \text{ feet} \)
- Length B (5 inches):
\( 5 \text{ inches} \times 3 \text{ feet/inch} = 15 \text{ feet} \)
- Length C (10 inches):
\( 10 \text{ inches} \times 3 \text{ feet/inch} = 30 \text{ feet} \)
Now, let's examine the given statements:
1. **Length A of the magazine's garden is 28 ft.**
- True (Calculated earlier)
2. **Length A of Imogen’s garden is 28 ft.**
- False (It's actually 24 ft)
3. **Length B of the magazine’s garden is 17.5 ft.**
- True (Calculated earlier)
4. **Length B of Imogen’s garden is 18 ft.**
- False (It's actually 15 ft)
5. **Length C of the magazine’s garden is 35 ft.**
- True (Calculated earlier)
6. **Length C of Imogen’s garden is 20 ft.**
- False (It's actually 30 ft)
Therefore, the true statements are:
- Length A of the magazine's garden is 28 ft.
- Length B of the magazine's garden is 17.5 ft.
- Length C of the magazine's garden is 35 ft.
