<PRE><B>Question 952475</B>
Area: A
One base: a
Other base: b
height: h
Area of the trapezoid: {{{A=((a+b)/2)h}}} Multiply both sides x 2:
{{{2A=(a+b)h Divide both sides by (a+b):
{{{(2A)/(a+b) = h}}} Substitute, using numbers in the problem:
{{{(2(150))/(14+16)= h}}}
{{{(300/30) = h}}}
10 = h, rewrite to make it pretty:
h = 10 This is the height of the trapezoid.
