I tried to include some explanations as well. Hopefully this helps.
Rounding to the nearest hundredth would equal a more accurate and precise answer since more decimals are present. Your answer would be even more accurate if you rounded to the nearest thousandth.
Answer:
3.6 ft = 43.2 inches
3.6 ft = 1.2 yards
Explanation:
Every foot is 12 inches. 3.6 * 12 = 43.2
To find yards, divide the feet by 3.
3.6 / 3 = 1.2
The triangles are NOT similar.
If they were the ratios of the sides would be the same.
3 / 4 = .75
5 / 6 = .8333333333
6 / 8 = .75
The answer is 9+10 your answer should be solved
