, where 
is the trapezoid's area, 
and 
are the trapezoid's bases, or parallel sides, and 
is the trapezoid's height. 
, and from the diagram, we see that 
. Therefore, all we have to do to find 
is substitute the given values into the area formula. Therefore:
(Substitute the given values into the equation)
(Simplify RHS)
(Divide both sides of the equation by 
to get rid of 
(Simplify, Symmetric Property of Equality)
