i NEED HELP wit a math problem!?

Question

This is for a project but how do you find the area of the blade or a ice skate if the blade doesn't form any kind of polygon?

please explain your answer!
THANXXX!

Answer 1

Create a polygon (rectangle) that is large enough so that the blade will fit into the interior.

Then subtract from the area of the rectangle the area of the that falls outside the rdges of the blade.

That will give you the area of the blade.

How to:

Take a piece of paper that is large enough to trace the blade on.

Trace the blade.

Then take a ruler and draw a box around the shape of the blade such that the entire blade tracing is inside the box.

Then take your ruler and break up the extra space into shapes that you can compute the area, and all up the areas of all the small shapes.

Then take the area of the rectangle, subtract the total areas of the small shapes, and the answer is the area of the blade.

If you need cubic inches, measure the thickness, take the area of the blade times the thickness and you have the cubic inches.

Hope this helps!

Answer 2

If understand this right, you should be able to break up the two-dimensional profile into polygons that are easier to calculate and then add up the individual areas to get the total area.

Answer 3

approximate the area by using many small common polygons. find the areas and add them together.

Answer 4

what area do you need ?
I suppose you need the area that touches the ice.
that area is approximatly a rectangle, very small about 2 millimeters, and length about 20 ~ 25 centimeter

ah

and it is not pic, but picture
