The equation of the ellipse that has a center at (7,4), a focus at (10,4), and a vertex at (12, 4), is (x - C)^2/A^2 + (y – D)^2/B^2 = 1

where
A=
B=
C=
D =

i can't read the graph

step-by-step explanation:

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .

if i did my math right then the answer should but 108

the correct answer for this just to make it clear for you guys is 2,3
