Question

What is the area of this trapezoid?

Answer 1

The formula of an area of a trapezoid:

`A=(base_1+base_2)/(2)\cdot height`

We have

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

Substitute:

`A=(25+19)/(2)\cdot20=(44)/(2)\cdot20=22\cdot20=440\ cm^2`

Answer 2

400cm^2

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
