I can't estimate the perimeter without any values, but as for the rounding...
Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the tenths place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
Circle = Circumferance. Triangle = Perimeter. Perimeter for a Triangle, you count up the number of units on it.
Estimate what to the nearest whole number?
If you have an exact number what is the need for an estimate?To the nearest whole number, it is 1; to the nearest ten (or larger) it is 0.If you have an exact number what is the need for an estimate?To the nearest whole number, it is 1; to the nearest ten (or larger) it is 0.If you have an exact number what is the need for an estimate?To the nearest whole number, it is 1; to the nearest ten (or larger) it is 0.If you have an exact number what is the need for an estimate?To the nearest whole number, it is 1; to the nearest ten (or larger) it is 0.
I estimate that the nearest whole number to 5 is either 4 or 6.
You can't tell. There are an infinite number of triangles that all have a perimeter of 144.

That number is called the "perimeter" of the triangle.

2.5 to the nearest whole number is 3.
3
To the nearest whole number, 11
It would be 3-5-11 with internal angles of 19.7-28.1-132.2, and a perimeter of 23.
To estimate 44.25, you can round the number to the nearest whole number, which is 44. You can also round it to the nearest tenth, which is 44.3. Another way to estimate is to round it to the nearest hundredth, which is 44.25 itself. Each of these methods provides a different level of precision in estimation.
