Am presuming you are looking for the two insects.
In rounding up to nearest whole number, you look at the number before the decimal point, if the number after that is 5 or more, you add up one extra to the digit before the decimal point.
When you round up bumblebee 2.861 to the nearest whole number you have 3.
When you round up honeybee 2.548 to the nearest whole number you have 3.
The two insects are bumblebee and honeybee.
No other two are equal when rounded up to the nearest whole number.
<u>Given</u>:
Given that the regular decagon has sides that are 8 cm long.
We need to determine the area of the regular decagon.
<u>Area of the regular decagon:</u>
The area of the regular decagon can be determined using the formula,

where s is the length of the side and n is the number of sides.
Substituting s = 8 and n = 10, we get;

Simplifying, we get;




Rounding off to the nearest whole number, we get;

Thus, the area of the regular decagon is 642 cm²
Hence, Option B is the correct answer.
