+865 the area of a trapezoid is 128.4 feet. If the height of the trapezoid is increased by a factor of 5, what is the effect on the area?
+129899 Assuming that the bases remain the same....If the heght is increased by a factor of 5, then the area is also increased by a factor of 5
We can see this as follows
Area before increase = (1/2) h ( sum of bases)
Area after increase = (1/2) (5h) (sum of bases) = 5 [ ( 1/2)h (sum of bases ) ] = 5 times the original area
