Final answer:
a) Ratio: 3:4, x ≈ 9.6 feet. To solve this problem, set up a proportion by setting the two ratios equal to each other. For example, if the ratio is 3:4 and x is approximately 9.6 feet, the proportion would be 3/4 = 12/x. Cross multiplying, you get 3x = 48, and then solving for x, x = 16. This means that x is approximately 16 feet.
