When you plot the given points on a coordinate plane, you can see this is an ellipse that is vertical. The equation for this is
. Of the values a and b, a is always greater than b, so it is on our major axis, the y-axis (it's under the y-k). a is the distance from the center to the vertices. When you plotted those given points, you can see that point dead center between the foci and the vertices is the origin (0, 0). That gives us our h and k values of 0 and 0. a is the number of units from the h coordinate of 0 to the y coordinate of the vertex, so a = 12. c is the number of units from the center to the foci, so c = 11. We need to find b now using the formula for the foci which is
. We have c and a, so
and
. Now we have all the info we need to rewrite the equation:
or, simplified,
ANSWER:
area= length x width
16 x 12= 192 in

Answer:
the real distance from the shop to the store is
Step-by-step explanation:
we know that
The scale of the map is to
so
by proportion
find the real distance for a distance in a map of
therefore
the real distance from the shop to the store is
