Answer:

400cm^2

Step-by-step explanation

equation: a+b/2 x h

19+25/2 x 20

44/2 x 20

22 x 20

440 (don't forget unit) and to square because we are finding the area

gmany

The formula of an area of a trapezoid:

[tex]A=\dfrac{base_1+base_2}{2}\cdot height[/tex]

We have

[tex]base_1=25\ cm\\\\base_2=19\ cm\\\\height=20\ cm[/tex]

Substitute:

[tex]A=\dfrac{25+19}{2}\cdot20=\dfrac{44}{2}\cdot20=22\cdot20=440\ cm^2[/tex]
