Question from Steven, a student: I have been given a coursework in which i have to investigate various shapes to find the one that would give the largest area with 1000m perimeter. I'm stuck in a part where i have to calculate the area of a irregular pentagon. i don't know where to start from. I can make up the length of all the sides (5 sides), so long they add up to 1000, but i'm not quite sure what to do after that. |
Hi Steven,
Since this is an investigation I think you can decide on the shape of the irregular pentagon, as long as the perimeter is 1000 metres. I would use a shape that makes finding the area easy, like perhaps a house.
