Activity 3: A Real Step to Quadratic Equatic

Use the situation below to answer the questions that follow.
Mrs. Jacinto asked a carpenter to construct a rectangular
classroom. She told the carpenter that the boards area must be
1. Draw a diagram to illustrate the bulletin board.
2. What are the possible dimensions of the bulletin board? G
dimensions.
3. How did you determine the possible dimensions of the bull
4. Suppose the length of the board is 7 ft. longer than its wid
sent the given situation?
5. How would the equation formulated?
6. Do you think you can use the equation formulated to fin

 

Answer:

1. (Answer is on the picture)

2. Possible dimensions of the bulletin board: 2 ft. by 9 ft. and 3 ft. by 6 ft.

3. Find two positive numbers whose product equals 18.

(Note: Area = length x width)

4. Let w be the width (in ft.). Then the length is w + 7. Since the area is 18, then 187 . (Other variables can be used to represent the length or width of

the bulletin board)

5. Taking the product on the left side of the equation formulated in item 4 yields

w^2 +7w=18 . The highest exponent of the variable involved is 2.

6. Yes

Hope Itll be a big help.
