Answer:
Step-by-step explanation:
Find the Area of the Rectangle which is = wl
Width = 17ft
Length = 22ft
17 × 22 = 374ft
Subtract 374ft by the area of the no digging
Width = 17ft
Length = 6ft
17 × 6 = 102ft
374 - 102 = 272ft

The answer to your question is below
Step-by-step explanation:
Data
Center = (0, 0)
Vertex = (13, 0)
Focus = (12, 0)
Process
From the data we know that it is a horizontal ellipse.
1.- Calculate "a", the distance from the center to the vertex.
a = 13
2.- Calculate "c", the distance from the center to the focus
c = 12
3.- Calculate b
Use the Pythagorean theorem to find it
a² = b² + c²
-Solve for b
b² = a² - c²
-Substitution
b² = 13² - 12²
-Simplification
b² = 169 - 144
b² = 25
b = 5
4.- Find the equation of the ellipse
