Final answer:
The calculations have been performed, and the products are rounded to the appropriate number of significant figures as follows: a) 78.2 m², b) 12 m², c) 2.46 m², d) 81.1 m².
Step-by-step explanation:
The subject of this question is Mathematics and it pertains to performing multiplication operations with measurements, followed by rounding the products to the appropriate number of significant figures based on the precision of the given values.
- For 24 m x 3.26 m, multiply these two values to get 78.24 m². Round to the least number of significant figures in the original measurements, which is 3, resulting in 78.2 m².
- For 120 m x 0.10 m, the product is 12 m². The least number of significant figures is 2, so the rounded answer is 12 m².
- For 1.23 m x 2.0 m, multiply to get 2.46 m². Round to the least number of significant figures, which is 3, and the result is 2.46 m².
- For 53.0 x 1.53 m, multiply to get 81.09 m². The least number of significant figures is 3, which gives us a final answer of 81.1 m².
