answer:Ergonomics: A bridge between fundamentals and applied research.
Area of each side triangle is 1/2*8*15 = 60. There are 5 of them so the triangles have surface area 300. the pentagon's area 1/2*apothegm*sidelength*sides = 1/2*5.5*8*5 = 110. The total area is therefore 300+110 = 410
The answer is 540 because 32/48 is 2/3 and 360/540 equals 2/3
