For this case we have that by definition, the area of a rectangle is given by:

Where:
w: Is the width of the rectangle
l: is the length of the rectangle
According to the data of the statement we have:

Substituting:

Substituting the values:

Thus, we have two roots:
w_ {1} = \ frac {5+ \ sqrt {157} {2}} = 8.77
w_ {2} = \ frac {5+ \ sqrt {157} {2}} = - 3.77
We choose the positive value. So the width of the rectangle is approximately 8.77 meters and the length is 3.77 meters
Answer:

Answer:
50 black, 40 blue, and 20 red.
Answer:
Parallel
Step-by-step explanation:
In the slope-intercept form (y=mx +c), the coefficient of x tells us the slope of the line.
2x +8y= 56
Let's rewrite this equation into the slope-intercept form.
8y= -2x +56
Dividing both sides by 8:


Slope= -¼
y= -¼x -5
Slope= -¼
Since both lines have the same slope, they are parallel to each other.
