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}
