The equation a = startfraction one-half endfraction left-parenthesis b 1 plus b 1 right-parenthesis.(b1 + b2)h can be used to determine the area, a, of a trapezoid with height, h, and base lengths, b1 and b2. which are equivalent equations? check all that apply.
2a/h -b2=b1
a/2h-b2=b1
2a-b2/h=b1
2a/b1+b2=h
a/2(b1 +b2)=h
Answers: 3
represents area, 
represents height and 
represents the base lengths of the trapezoid.
by rearranging the equation to find an equivalent equation.
