Area of walls = 15*8 +16*8 =248 ft^2
less area of windows 2*(3*4)= 24 ft^2
Less area of doors 2*(3*7) = 42 ft ^2
248-66= 182 ft ^2
square feet of wallpaper = 182

        Calculations in the post by @mananth are incorrect.
        They are performed under the assumption that the bedroom has two walls - - - ha-ha-ha.
        I came to bring a correct solution.


Area of walls = 2*(15*8 + 16*8) = 496 ft^2

less area of windows 2*(3*4)= 24 ft^2

Less area of doors 2*(3*7) = 42 ft ^2

496 - 24 - 42 = 430 ft^2

square feet of wallpaper = 430

Solved correctly.
