Answer:

  • 280 yd²

---------------------

Find the area of the four walls:

  • A = Ph
  • A = 2(50 + 30)*16
  • A = 2560 ft²

Find the area of the (window and door) openings:

  • A = 4(24*30) + 36*80
  • A = 5760 in²

Convert it to ft² (1 ft = 12 in):

  • 5760*(1/12)² =
  • 5760*1/144 =
  • 40 ft²

Subtract it from total area of walls:

  • 2560 - 40 =
  • 2520 ft²

Convert the area to be painter to square yards (1 yd = 3 ft:

  • 2520 ft² =
  • 2520*(/3)² =
  • 2520*1/9 =
  • 280 yd²
