A walk in Marcus’s bedroom is 8 2/5 feet high and 16 2/3 feet long. If he paints 1/2 of the wall blue, how many square feet will be blue?
To paint the wall blue, Marcus needs to cover an area that is 8 2/5 feet high and 16 2/3 feet long.
To find the area of the wall, we need to multiply the height by the length: 8 2/5 * 16 2/3 = 42/5 * 50/3 = 42 * 50 / 5 * 3 = 20 * 50 = <<42/5*50/3=1400>>1400 square feet.
Since Marcus is painting 1/2 of the wall blue, the blue area will be 1/2 * 1400 = <<1/2*1400=700>>700 square feet. Answer: \boxed{700}.
To find the area of the wall that Marcus painted blue, we need to multiply the height by the length and then multiply that product by 1/2 (since he painted only half of the wall blue).
The height of the wall is 8 2/5 feet, which is equivalent to 42/5 feet.
The length of the wall is 16 2/3 feet, which is equivalent to 50/3 feet.
So, the area of the wall is (42/5) * (50/3) = (42 * 50) / (5 * 3) = 210/3 = 70 feet.
Finally, to find the area that Marcus painted blue, we need to multiply the area of the wall by 1/2:
70 feet * 1/2 = 70/2 = 35 square feet.
Therefore, Marcus painted 35 square feet of the wall blue.
