Notice that we can figure the area of this triangle in two ways

 

One of the bases  = 20....and the height to this base = 12

So the area  is  (1/2) 20 * 12  =   120  units^2

 

Also.....the other base  = 30  and the height of this base   = h

So

 

Area  of triangle  = (1/2) * 30 * h

 

120  =  15 * h        divide both sides by  15

 

8 ft   =  h

 

 

cool cool cool
