The function for the trapezoid area is:
A(x)=(B+b)*h/2
where B and b are the bases and h is the
height.
With the given data:
h=10
B and b =7 and x (it may vary which one is
bigger)
So that function becomes:
A(x)=(7+x)*10/2
A(x)=(7+x)*5
So if you want the inverse function, you
have to operate to find x:
A(x)/5=7+x
A(x)/5-7=x
So the new function is:
x(A)=A/5-7

How many times does 245 go into 8? none.
into 84? none.
into 843? 3
So the first digit of the quotient is 3. Mult. 245 by 3, getting 735. Subtr. this amount from 843. Result: 108. How many times does 245 go into 108?
none. Bring down a zero, forming 1080. How many times does 245 go into 1080? 4, with remainder 100. And so on.
Please try doing this problem yourself, by hand.
