The equation below shows the area of a trapezoid, a, with a height of 9 cm, and one base 35 cm.

a = 9 over 2(b + 35)

which of the following formulas correctly solves for the other base, b?

b = 2a over 9 + 35

b = 2 multiplied by a over 9 - 35

b = 2 multiplied by a plus 35, all over 9

b = 2 multiplied by a minus 35, all over 9
