Discussion Overview

The discussion revolves around methods for understanding and solving GCSE Maths questions, particularly focusing on perimeter calculations. Participants seek simple explanations and examples to aid in their revision for upcoming tests.

Discussion Character

  • Homework-related
  • Debate/contested

Main Points Raised

  • One participant requests help with a specific Maths question, indicating a need for simple methods of explanation.
  • Another participant suggests that the perimeter of a shape is found by multiplying all the sides together.
  • Contrary to the previous claim, another participant asserts that the perimeter is found by adding the lengths of the sides, providing an expression of 6x + 8 as an example.
  • A later post seeks clarification on how to arrive at the expression for the perimeter.
  • Another participant presents a practical example involving a triangular park, asking for the total distance walked around it based on the lengths of its sides.

Areas of Agreement / Disagreement

There is disagreement regarding the method for calculating perimeter, with some participants advocating for multiplication of sides and others for addition. The discussion remains unresolved as participants provide differing methods without reaching consensus.

Contextual Notes

Some assumptions about the definitions of perimeter and the shapes involved may be implicit, and there are unresolved mathematical steps in the explanations provided.

I'm doing some Maths revision for my impending GCSE tests later this year. I have a (few) question(s) that I need explained to me in very simple easy methods.

Beware - there will probably be more questions.

Thanks peeps. Here's the first question I need help with.

Yucky, get a new scanner.

How do you find the perimeter of a shape?
 
Multiply all the sides together.

example:

Side 1 * side 2 * side 3 = perimeter.
 
no, add the sides together, here it is 6x+8.

Would you mind showing me how you done that, please? :cry:
 
If you walk around a park in the shape of a triangle, how far doy ou walk if the sides are 20m, 30m, and 40m? You walk 20m to get from one corner to the next, then from that corner to the second corner you walk 30m, and then from the second to your starting pointyou walk 40m. The distance you walked is _____ ?
