A trapezoid has one base equal to its height, x, and the other base is twice as long.
Write the expression for the area of the trapezoid as a common fraction in terms of x.

h  =    x

b1 =   x

b2 = 2x

 

Area  =  ½·h·(b1 + b2)   --->   Area  =  ½·x·(x + 2x)    --->   Area  =  ½·x·(3x) 

                                     --->   Area  =  (3/2)·x2
