What is the area of the trapezoid?

100 m^2.

Step-by-step explanation:

The area of a trapezoid = (h/2) (a + b) where h = the perpendicular distance between the 2 parallel sides and a and b are the lengths of the 2 parallel sides.

Here we have Area = (1/2 * 10) ( 8 + 12)

= 5 * 20

= 100 m^2.

100

Step-by-step explanation:

So first you add the two bases 12+8=20. Then you multiply the sum to the height 20×10=200. Lastly, you divide that number by two 200÷2=100.
