Answer by Nate(3500) (Show Source): You can put this solution on YOUR website!
By using the distance formula, you get the two bases as 6 and 4 units long. Also, you get the width as 4 units long.
The formula for a trapezoid is: A=.5(b+b)(w) where 'b' are the bases and 'w' is the width
A=.5(10)(4)=20
The answer is (b.).
