Last week I entered a math competition and one of their questions was. There is a hexagon with each side with length of 5 cm. What is the total length of all of its diagonal. I was really put off by this question, but then I thought that diagonals would cut each other and make 90 degree angles each.
Then I know one side is 5 cm, and its a 90 degree angle, so it'd be like 45 45 90 triangles, in which the ratio is 1, 1, square root of two respectively.
Doing then all the proportion and math, i got 15 multiplied by square root of two or approximately 21.213 Is there any math expert out there who can verify my answer, help is appreciated
Thank you. Hope it all makes sense.
