A wall in Marcus bedroom is 8 1/3 feet high and 16 1/5 feet long. If he paints 1/3 of the wall blue, how many square feet will be blue? I just need a quick answer no explanation needed

Sagot :

Answer:

45 square feet

Explanation:

• Height of the wall = 8 1/3 feet

,

• Length of the wall = 16 1/5 feet

First, find the area of the wall.

[tex]\begin{gathered} \text{Area}=\text{Length}\times Height=8\frac{1}{3}\times16\frac{1}{5} \\ =\frac{25}{3}\times\frac{81}{5} \\ =135\text{ square ft} \end{gathered}[/tex]

If he paints 1/3 of the wall blue, the area painted blue is:

[tex]\begin{gathered} \text{Area painted blue}=\frac{1}{3}\times Area\text{ of the wall} \\ =\frac{1}{3}\times135 \\ =45\; ft^2 \end{gathered}[/tex]

45 square feet of the wall will be blue.
