Why is it important to estimate the perimeter before finding its exact measurements Third grade answer?

It can help you get an idea what the real answer is. And if your real answer is way off or not. For example, let's say you want to multiply 3 x 9. Estimating the answer would be 3 x 10 which is 30. If you did the real multiplication and came out with 43, are you close to your estimate? No, you're way off! So it cannot be right.

∙ 8y agoOne way that estimation (before finding exact answer) helps - if you estimated an answer, and your calculated answer is much different, it indicates that you might have made a mistake in your figuring.

∙ 8y agoIn general, in math problems, an estimate can tell you whether the calculated "exact" answer is reasonable - this helps, in case you make an error.

How do you solve perimeter of a triangle?
You find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.
What is the formula for finding perimeter of a rhombus?
Perimeter = 4*n whereas n is the length of its side
Formula of a perimeter?
The formula for finding out perimeters of shapes is length+length+height+height=perimeter or what else you can do is (lengthx2)+(heightx2)=PERIMETER
When finding the perimeter of a figure on a grid why do you not count the spaces inside the grid?
That's because "perimeter" means the distance around something - not the spaces inside. If you count squares inside a figure, you are finding the AREA, not the PERIMETER.
What is the formula for finding the perimeter of a s quare?
Perimeter of square = 4 x L where L = length of one side of the square.
Why is finding the perimeter of a triangle related to finding the perimeter of a rectangle?
It is not in all but a trivial sense - that they are both to do with finding the perimeter!
How do you measure area perimeter?
If you're trying to measure the perimeter of almost any shape like a square or triangle or octagon, simply count all the unit measurements of each side and add them together. If the unit your measuring is unknown, then leave it as units. For example, if you were finding the perimeter of a rectangle that has the measurements 6units, 6units, 4units, and 4units, the perimeter would be 20units. I hope this helped :)
What is the difference between finding the perimeter of a polygon and finding the area of a polygon?
Finding the perimeter of a polygon is finding how far it is in total along all the edges of the polygon; whereas finding the area of a polygon is finding how much space the polygon covers. The perimeter of a polygon forms the boundary around the area of the polygon.
What is the formula for finding the perimeter of a trapazoid?
Perimeter = sum of lengths of sides.
How do you solve perimeter of a triangle?
You find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.
When finding the perimeter do you add?
Yes, for the perimeter of a polygon, you add up all the sides.
What is the formula for finding perimeter of a rhombus?
Perimeter = 4*n whereas n is the length of its side
Are the units for finding perimeter always square?
No, perimeter is always measured in units of length (L)
Formula of a perimeter?
The formula for finding out perimeters of shapes is length+length+height+height=perimeter or what else you can do is (lengthx2)+(heightx2)=PERIMETER
How do you find perimeter of a quadrilateral after finding midpoints?
If you want the perimeter of a quadrilateral, then finding the midpoints is a complete waste of time! Simply add together the lengths of the four sides.
When finding the perimeter of a figure on a grid why do you not count the spaces inside the grid?
That's because "perimeter" means the distance around something - not the spaces inside. If you count squares inside a figure, you are finding the AREA, not the PERIMETER.
What do you call the perimeter of a circle?
The perimeter of a circle is called the circumference and the formular of finding it is Pi D or 2Pi R
