I really don't get what you're asking but in finding the new area 20 feet and 10 feet I found the area and the perimeter 14 cm2. I have found both perimeter and area so if you wanted an answer I guess it is in one of my answers.

Find the area of the following ellipse. a = 4.5 m; b = 5.5 m

LenaWriter [7]

Answer:

Area of ellipse is ≈ 77.78 $m^{2}$

Step-by-step explanation:

Given the dimension of ellipse

a = 4.5 m

b = 5.5 m

Now, Area of ellipse = $\pi ab$

= $\frac{22}{7}\times 4.5\times 5.5$

= $\frac{5445}{70}$

= 77.78 $m^{2}$

Hence Area of ellipse will be 77.78 $m^{2}$
