Ok
1. The area of the trapezoid = 1/2 (base1 + base 2) * height
____________________________________________--
Part A
In this case to find the shaded area you just need to calculate the area of the inner and the outer trapezoid and then subtract the area of the inner trapeze from the area of the outer
So the answer is the b choice
_______________________
Part B
the values
Inner trapezoid
base 1 = 2
base 2 = 4
height = 3
the inner trapezoid area = 1/2 (2 +4) 3
=3*3
= 9
Outer trapezoid
base 1 = 2
base 2 = 6
height = 6
the outer trapezoid area =1/2 (2 +6) 6
=4*6
= 24
_________________________________
cthe outer trapezoid area - the inner trapezoid area
the inner trapezoid area = 24 - 9
the inner trapezoid area = 15 (units^2 or square units)
