Question 39676: I cant figure out how to solve the literatal equation for the indicated variable.
A = 1
__
2h (B +b) (FOR b)
area OF TRAPEZOID.
Answer by fractalier(6550)   (Show Source):
You can put this solution on YOUR website! The area of trapezoid is given by
A = (1/2)h(B + b)
To solve for the smaller base,b, we need to isolate it...
First multiply both sides by two, then divide by h, then subtract B, and we get
A = (1/2)h(B + b)
2A = h(B + b)
2A/h = B + b
b = (2A/h) - B
