How many square feet are in the painting? ** First find the area of the painting: 2 feet * 4 feet = <<2*4=8>>8 square feet
How many square feet are in the wall? ** Then find the area of the wall: 5 feet * 10 feet = <<5*10=50>>50 square feet
How much of the wall is taken up by the painting? ** Then divide the area of the painting by the area of the wall and multiply by 100% to express the answer as a percentage: 8 square feet / 50 square feet * 100% = 16%
