3(k-x)= -3x-9
3k - 3x = -3x - 9 ← equation without parentheses
3k - 3x + 3x = - 9
3k = -9
k = -9/3
k = -3 ← simplest form

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 $m^{2}$
