Question

What is the area of this trapezoid?

Answer 1

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

Answer 2

The formula of an area of a trapezoid:

$A=\dfrac{base_1+base_2}{2}\cdot height$

We have

$base_1=25\ cm\\\\base_2=19\ cm\\\\height=20\ cm$

Substitute:

$A=\dfrac{25+19}{2}\cdot20=\dfrac{44}{2}\cdot20=22\cdot20=440\ cm^2$
