If you would like to know how many square feet of the wall will be blue, you can calculate this using the following steps:

8 2/5 feet high * 16 2/3 feet long = 8 2/5 * 16 2/3 = 42/5 * 50/3 = 140 square feet

1/2 * 140 = 140/2 = 70 square feet

The correct result would be 70 square feet.

The area that will be painted blue is 69.97 square feet.

How to find the area that will be painted blue?

Remember that for a rectangle of length L and width W, the surface area is given by:

[tex]A = L*W[/tex]

In this case we have:

  • L = (8 + 2/5)ft
  • W = (16 + 2/3) ft.

Replacing that in the area equation:

[tex]A = (8 + 2/5)ft*(16 + 2/3)ft = (8.4 ft)*(16.66ft) = 139.94 ft^2[/tex]

And we know that half the wall is painted, so the area that will be blue is:

[tex]B = (139.94 ft^2)/2 = 69.97 ft^2[/tex]
