Mr. Cayetano plans to install a new exhaust fan on his room’s square-shaped wall. He asked a carpenter to make a square opening on the wall where the
exhaust fan will be installed. The square opening must have an area of 0.25 m2
1. Draw a diagram to illustrate the given situation.
2. How are you going to represent the length of a side of the square-shaped wall? How about its area?
3. Suppose the area of the remaining part of the wall after the carpenter has made the square opening is 6 m2. What equation would describe the area of the remaining part of the wall?
4. How will you find the length of a side of the wall?
