The area of a rectangle is obtained through the equation,
A = L x W
The width of the yard is 4 ft less than the length and may be expressed as L - 4. Length may be solved through the following steps,
A = (L)(L-4) ; 96 = L(L - 4) ; L = 12 ft
The length and width are 12 ft and 8 ft, respectively. Perimeter may be solved through the equation,
P = 2 x (L + W)
Substituting the values of L and W
P = 2 x ( 12 ft + 8 ft) = 40 ft
Therefore, the perimeter of the yard is 40 ft.
Answer:
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width.
You know that the ratio of the sides of the rectangular window is:
Then, let be 
the width (in inches) of the rectangular window and 
the lenght (in inches) of the rectangular window.
Knowing that the area of the window is 2,720 square inches, you can know that:
Now you must solve for "x" in order to find the width:
Finally, the lenght is:
This is a fun problem! Just graph the two equations, then see what points the line intersects with the parabola. Or, set the two equations equal to each other, and solve for the two intersecting points.
Solve for x and y: -2x+8 = x-2.23y+10.34
