Answer: 1204 cm²
Explanation:
The upper bound of the area of a page would be the area of a rectangle with the upper bound of the length and width measurements.
Given that each page of the newspaper is a rectangle measuring 43 cm by 28 cm, both correct to the nearest centimetre, the upper bound of the length would be 43.5 cm (since we round up to the nearest centimetre) and the upper bound of the width would be 28.5 cm.
Therefore, the upper bound of the area of a page would be:
43.5 cm x 28.5 cm = 1240.25 cm²
Rounding this value to the nearest whole number, we get:
1204 cm²
So, the upper bound of the area of a page is 1204 cm².
