Find the areas of both the wall and the door and subtract the two
8 x 20 = 160
to find the width of the wall:
4+ 8+ 8= 20
Area of the wall:
25 x 20 = 500
Area to be painted:
500-160 = 340 ft^2
8 x 20 = 160
to find the width of the wall:
4+ 8+ 8= 20
Area of the wall:
25 x 20 = 500
Area to be painted:
