Question

Betsy wants to paint the walls of a square closet. Her closet walls measure 10 feet long and 8 feet high. Each wall is the same length and height. How many square feet is Betsy painting?(Hint: She is painting all four walls.)320 ft^280 ft^2128 ft^2160 ft^2

Answer 1

`A_(closet)=320\text{ square ft}`

Explanation:

The area of a rectangle is represented by the following equation:

`A=\text{ length}\cdot\text{height}`

Therefore, if the walls are 10 feet long and 8 feet high, and there are 4 walls:

`\begin{gathered} A_(closet)=4\cdot(10\cdot8) \\ A_(closet)=320\text{ square ft} \end{gathered}`
