Solution:
As, You have Written Polygon ABCD is a rectangle.
It is a Four sided Polygon , having all it's interior angles equal to 90°.As well as Opposite sides are equal(AB=CD,AD=BC), equal diagonals(AC=B D).
Join any of the diagonal of Rectangle either AC or B D.
In Right Δ ABC , Right angled at B
---(1)
In Right Δ ADC , Right angled at D
---(2)
Adding (1) and (2) that is LHS to LHS and RHS to RHS
Ar( Δ ABC) +Ar( Δ ADC)
So, Area of Rectangle= Product of any two Adjacent Sides
Given the two options above, in order to come up with the best plan we have to calculate the future value of money in each plan.
compound interest is given by:
Option 1
p=$500
r=2%=0.02
t=1 year
Option 2
p=$500
r=2/12=1/6
n=1*12=12
hence:
=$509.09
Comparing the two plans above, option 1 is the best.
b] Option 1 is the best because she will secure $510 as compared to option 2 which has interest rate that reduces her amount by $1 after one year due to annual charges. The total amount of money she will have at the end of the plan is $510.

Answer:
<u>20,602 feet</u> is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.
Step-by-step explanation:
Given:
Mt. McKinley, which is the highest elevation in North America, is 20,320 feet above sea level.
Death Valley, which is the lowest elevation in North America, is 282 feet below sea level.
Now, to find the difference in height between the top of Mt. McKinley and the bottom of the death valley.
<em>Height of Mt. McKinley above sea level = 20,320 feet.</em>
<em>Height of Death Valley below sea level = 282 feet.</em>
Now, to get the difference in height between the top of Mt. McKinley and the bottom of the Death Valley by adding both the heights:
Therefore, 20,602 feet is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.
