Answer:
The given equation is
Which represents an elipse.
To find its elements, we need to divide the equation by 100
Where and
. Remember that the greatest denominator is
, and the least is
. So, we extract the square root on each equation.
and
.
In a elipse, we have a major axis and a minor axis. In this case, the major axis is vertical and the minor axis is horizontal, that means this is a vertical elipse.
The length of the major axis is .
The length of the minor axis is .
The vertices are and
.
Now, the main parameters of an elipse are related by
, which we are gonna use to find
, the parameter of the focus.
So, the coordinates of each focus are and
The eccentricity of a elipse is defined
The latus rectum is defined
Finally, the graph of the elipse is attached.
Assuming the shape of the room is a rectangle :
Area = Width x Length.
Let's call width "w" and length "l" . Now if, the width is 4/5 of the length that means 4/5 times length gives us the width, like this :
As given in the question, area of the rectangle is 320 square feet. And as I said before area of a rectangle can be found by multiplying its length and width.
, we can plug w's value in the previous equation to find "l".
Let's plug "l"s value in the equation.
The length is 20 feet and the width is 16 feet.
Area = Width x Length.
Let's call width "w" and length "l" . Now if, the width is 4/5 of the length that means 4/5 times length gives us the width, like this :
