Question

The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h

Answer 1

Answer:

The answer is b=2A/h-a

Answer 2

Given that the formula for a trapezoid that relates the area A, the two bases, a and b, and the height, h is given by:

$A= \frac{h(a+b)}{2}$

To solve for b, first multiply both sides by 2 to get:

2A = h(a + b) = ah + bh

Next, subtract ah from both sides to get:

2A - ah = bh

Next, divide both sides by h, to get:

$\frac{(2A-ah)}{h} =b \\ \\ \therefore b=\frac{2A-ah}{h}$
