Hello! :) 

We can use the following area to solve for the area of the trapezoid pictured:

Where:
h = height
b1 = bottom base
b2 = top base
Plug in the given values:

Simplify:

 
        
             
        
        
        
Answer:
Not larger or smaller; the areas are the same
Step-by-step explanation:
Recall that the formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
In the first case, h = 3 ft and b = 2.5 ft.  This results in an area of 3.75 ft^2.
In the second case, h = 2.5 ft and b = 3 ft.  The area is the same:  3.75 ft^2.
This is because A = (1/2)(b)(h) has the same value regardless of the order in which b and h  are used as multipliers.
There is no difference in the areas of the two signs.  The areas are the same.
 
        
             
        
        
        
10 years, because In 5 years after 2008, 2013 you get new math books 5 more years you get another set of math books-2018, but 2008 plus 10 years you get science books which is also 2018 which is also when you get another set of math books. So the next year you get math books and science books shipped the same year is 2018. 2018-2008=10 so 10 years pass

Answer:
A trapezoid has one pair of parallel sides and a parallelogram has two pairs of parallel sides. So a parallelograms are also trapezoids.
