Best ResponseYou've already chosen the best response.12. Draw FBCE with BC at the top, at FE as the base. Draw lines straight down from B and C to FE, to form triangles with angles, 45, 45, 90. This is a 1:1:sqrt(2) triangle the length of each of the sections is 6 / sqrt(2) = 3 * sqrt (2) There are 2 of the triangles. 12  2 * (3 * sqrt (2)) = 12  6 sqrt(2) = 12  8.485 = 3.5
