Question 38320: What is the area of s trapezoid with vertices(-3,-1), (3,3), (-1,3) and (3,-1)?
a.24 square units
b.20 square units
c16 square units
d.12 square units 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.).
