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 = ?
