Awall 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 find the area of the walk in Marcus's bedroom, we have to use the formula: A = b * h. However, to multiply these two values, we should first transform them into improper fractions.

8 2/5 : 8 * 5 = 40 + 2 = 42/5

16 2/3 : 16 * 3 = 48 + 2 = 50/3

Now, we can begin to solve the problem.

Area of Wall = base * height

Area = (50/3) * (42/5)

Now, we simply multiply the fractions.

Area = 140 square feet

However, this value represents the area of a whole wall of Marcus's room. To find the area of the 1/2 of the wall that he plans to paint blue, we must multiply this value by 1/2.

140 * 0.5 = 70 square feet

Therefore, Marcus is going to paint 70 square feet of the wall blue.
