Question

The area of a trapezoid is given by the formula A =1/2 (b 1 + b 2)h, where base b 1 is parallel to base b 2 and h is the height. Solve the formula for b 2. Show your work.

Answer 1

A= 1/2 x (b1 + b2) x h
2Ah = b1 + b2
2Ah -b1 = b2

Answer 2

thats the answer

Answer 3

yup b2= 2Ah - b1

Answer 4

why is it 2AH, isn't it (2A)/h ?

Answer 5

oh yah...my mistake...

Answer 6

The correct formula would be:
\[\frac{ 2A }{ h } - b1 = b2\]

Answer 7

thanks
