A wing has a planform area S of 100 ft^2 and a total span b of 20 feet. The same symmetric airfoil is used all along the span. The wing is untwisted, untapered, and swept back at 30 degrees. The freestream Mach number is 0.5. Sketch the planform you would use to analyze this wing in a low speed (incompressible) wind tunnel. Show all dimensions (root, tip, semi-span), and the leading edge sweep.
