Discussion Overview

The discussion revolves around calculating the area of a shape that was initially thought to be a square with an area of 490 mm². Participants explore the geometry involved and clarify the nature of the shape in question.

Discussion Character

  • Homework-related, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant expresses difficulty in calculating the area, suggesting it should be simple geometry.
  • Another participant questions the validity of the shape being a square, noting discrepancies in the measurements provided and applying Pythagorean theorem to check the diagonal.
  • A third participant acknowledges the initial confusion about the shape, indicating that it is not a square and mentions having found a solution independently.
  • A fourth participant seeks assistance with calculating the area of a different, unspecified shape.
  • A fifth participant comments on the relevance of the new question to the original thread, suggesting it may be better suited for a separate discussion.

Areas of Agreement / Disagreement

There is no consensus on the nature of the shape being discussed, with some participants questioning its classification as a square and others indicating it is not. The discussion remains unresolved regarding the correct approach to calculating the area.

Contextual Notes

Participants have not clearly defined the shape in question, and there are unresolved aspects regarding the measurements and their implications for area calculation.

Hello!

This is pretty easy but i´m failing...

The area of this "square" should be 490 mm2 .
What the proper way to do this..., I guess its simple geometry but for the moment I am drawing blank...

Something is wrong in your image, when I consider the number all the way at the bottom to be the length of a side... using Pythagoras to calculate the diagonal length doesn't give me the indicated value.
Is it really a square? What precisely measures 22.3?
 
No, its nor really a square. Yes, it was a pretty crappy picture, but I got to the solution on my own. thanks for the help
 
I need help with normal shape area. Anyone?
 
WadeS, welcome to PF :smile:

It would have been best to ask your question in a brand new thread, since it appears unrelated to what was asked here.

That being said, what shape is it you need help with finding the area?:confused:
