Perimeter = 2(3.9) + 2(.9) + 6(1.3) = 12(1.3)+1.8 = 15.6+1.8 = 17.4 m
Area = 1.3(3.9) + .9(3.9) =2.2(3.9) = 8.58 m^2
(this assumes the horizontal distance at the bottom = 1.3 and the horizontal distance at the top = 3.9
while the diagram doesn't expressly indicate that, visually the distance does seem to be exactly that)
