Final answer:
Without additional context, any of the provided options (a, b, c, or d) could be the correct dimensions of the zoo enclosure. The question is a basic geometry problem in mathematics where understanding dimensions is key.
Step-by-step explanation:
The question regarding the dimensions of a rectangular enclosure at the zoo is a matter of reading and understanding the given options for dimensions. Since the question does not provide additional information that would allow us to determine which set of dimensions is correct, any option provided in the question can be valid. This is a geometry problem commonly found in middle school mathematics. For instructional purposes, let's illustrate how one could handle a similar problem involving scale drawings and converting real-life measurements into a scaled model.
For example, if Rano wants to create a scale drawing of his 50 feet by 30 feet backyard using the scale 1/2 inch equals 5 feet, you would calculate the scaled dimensions as follows:
- Understand the scale: 1/2 in = 5 ft.
- Convert the actual dimensions to the scale:
- Length: 50 ft ÷ 5 ft/in = 10 in.
- Width: 30 ft ÷ 5 ft/in = 6 in.
Resulting scale drawing dimensions: 10 in. by 6 in.
The question does not provide enough information to definitively choose an option for the zoo enclosure's dimensions. Hence, options a) 35 ft x 18 ft, b) 18 ft x 35 ft, c) 40 ft x 20 ft, and d) 20 ft x 40 ft, are all mathematically valid as potential dimensions of the enclosure without further context.
