Investigating Adidas

Level pending

Dan wants to create the Adidas logo by cutting three strips of same sized rectangles with the width 6, labelled A B C D , E F G H , K L M N ABCD, EFGH, KLMN respectively. Then, he cuts the strips diagonally, at Q R QR , such that cos B Q R = 0.5 \cos\angle BQR=0.5 . This process continues at the other two rectangles, at S T ST and U V UV respectively, by satisfying cos F S T = cos L U V = 0.5 \cos\angle FST = \cos\angle LUV=0.5 . If the ratio of the area of the trapeziums is [ A B Q R ] : [ E F S T ] : [ K L U V ] = 65 : 34 : 13 [ABQR]:[EFST]:[KLUV]=65:34:13 , and the sum of the areas is 336, then find B Q + F S + L U \lfloor BQ+FS+LU\rfloor if B Q > A R , F S > E T , L U > K V BQ>AR, FS>ET, LU>KV .
