I havent done trigonometry for over 3 years.. lets see if it stuck...
lengthOfDiagType1 = 5 / (sin 120) = 5.7735 (From sin 120 = 5 / Hypoteneuse)
lengthOfDiagType2 = 2 * sideLength = 2 * 5 = 10
count(diagType1) = 6
count(diagType2) = 3
(6 * lengthOfDiagType1) + (3 * lengthOfDiagType2) =
64.641 cm (to 3 dp)
Could someone check that please, its very possible that i got it wrong hehe.
No pythagoras here zen_tom
P.S. sorry i listed it like a program, thats just what i'm good at...
