Step-by-step explanation:
A trapezoid is a quadrilateral which has its base parallel to the opposite side. It's area can be determined by;
Area of trapezium =
(
+
)h
Where
is the measure of length of its fist base,
is the measure of its second base and h is its height.
Considering the given question,
Term =
+ 
Coefficient = 
Constant = 
Factor =
