75 (125 + 81) / 2
In other words use the average height
to show why draw verticals at the two ends of the short top
you cut off identical triangles at the ends
put those triangles together now and look at the area added to the interior rectangle by them,

area of trap = (1/2)(sum of bases)(height between the bases)
= (1/2)(125+81)(75)
= ..... ft^2
= (1/2)(125+81)(75)
= ..... ft^2
