Many students struggle to understand the answer key to the fifth problem of the fifth homework of lesson three. Fortunately, this article provides a comprehensive answer key to this problem so that students can move on to other tasks.

## The Problem The fifth problem of the fifth homework of lesson three is as follows: Write an equation that represents the situation: The area of a rectangular room is 96 square feet and the length is 8 feet. The equation for this problem is A=L*W, where A is the area, L is the length, and W is the width. Therefore, the equation for this problem is A=8*W.

## The Solution The solution to this problem is as follows: Solve for W. To solve for W, divide both sides of the equation by 8. Therefore, W=A/8. Substitute 96 for A and the equation becomes W=96/8. Simplify the equation to W=12. Therefore, the width of the room is 12 feet.

## The Solution in Action It is always helpful to see the solution in action. To do this, substitute 12 for W in the original equation. The equation becomes A=8*12. Simplify the equation to A=96. Therefore, the area of the room is 96 square feet, which is what the problem stated.

## 

The answer key to the fifth problem of the fifth homework of lesson three is W=12. This can be verified by substituting 12 for W in the original equation and simplifying it to A=96. With this answer key, students can confidently move on to the next problem.
