In order to find b1 from your formula stated we need to do few calculations
A=hb1+hb2, as you wee I multiply h with both bases( b1 and b2)
I will subtract hb2 from both sides
hb1=A-hb2
now I will divide my new expression by h
b1=(A-hb2)/h
2 3 5 7 11 13 17 19 23 31 41 43 53 59

<u>Answer</u>:
The Area of the Ferris wheel is 31400 Square feet
<u>Step-by-step explanation:</u>
The AREA formula for a circle:
The Area formula for the circle is 
where
r is the radius of the circle
The area of the Ferris Wheel:
The Height of the Ferris wheel = 200 foot
Here height of the Ferris wheel is the diameter
So the Diameter = 200
Then Radius =
= 100 foot
Now the area of the Ferris wheel is
=> 
=> 
=> 31400 square feet
