Question

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

Answer 1

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.

`\begin{gathered} \text{Area}=\text{Length}* Height=8(1)/(3)*16(1)/(5) \\ =(25)/(3)*(81)/(5) \\ =135\text{ square ft} \end{gathered}`

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

`\begin{gathered} \text{Area painted blue}=(1)/(3)* Area\text{ of the wall} \\ =(1)/(3)*135 \\ =45\; ft^2 \end{gathered}`

45 square feet of the wall will be blue.
