I can't provide the answer. But...I can provide examples.
Hope these help!

Step-by-step explanation:
f(x) = x² - 3x + 2 = (x - 2)(x - 1).
When f(x) = 0, (x - 2)(x - 1) = 0.
=> x = 2 or x = 1.
Let the side length of the original square be x, then
1/4 x^2 = (x - 3)^2
x^2 = 4(x^2 - 6x + 9) = 4x^2 - 24x + 36
3x^2 - 24x + 36 = 0
3(x^2 - 8x + 12) = 0
x^2 - 8x + 12 = 0
x^2 - 2x - 6x + 12 = 0
x(x - 2) - 6(x - 2) = 0
(x - 6)(x - 2) = 0
x - 6 = 0 or x - 2 = 0
x = 6 or x = 2
but x cannot be 2 since the side length of the smaller square will be negative.
Therefore, the side length of the original square is 6 inches.
The blue ribbon would be 19 inches. We know the red ribbon is 12 inches and it’s 7 inches less than the blue one, so you would add 7 to 12 to figure out that the blue ribbon is 19 inches.
Answer:
40 square meters
Step-by-step explanation:
The area of the floor is 64 square meters. That means the square is 8 meters by 8 meters. Each side of the floor is 8 meters. Now a wall has an 8 meter side along the floor and a height of 5 meters. Each wall is a rectangle 8 m x 5 m with an area of 8 x 5 = 40 square meters.
