Trapezoid. Height is 16m, one base is
2
20m, and the area is 224 m what is the length of the other base?


The dimensions of area are m^2, not m.
I assume that your entry of "2" was a mistake, and that you meant 20m for one of the base lengths.

Trapezoid Area = (average base width) x height
= (1/2) (b1 + b2) h
b1 (the base width that you know)= 20
Area = 8(20 + b2)
= 224

20 + b2 = 224/8 = 28
b2 = ?
