/ ___ \ Let's imagine a trapezoid looks like this. The two parallel lines would be the top and the bottom lines.
The 10 in. side would be either the top or bottom line. The other parallel line is twice as long, meaning it's 2 times longer. So you multiply 10 in x 2 = 20 in.
The given side length = 10 inches.
Height = half as long, meaning it's half of 10 in. = 5 in.
Formula of a trapezoid =
x height
Where a and b are bases. The top and bottom of the trapezoid are bases.
Area trapezoid =
x 5 = 
x 5 = 15 x 5 = 75 in² <-- area means the unit is squared

Answer: 2,970
Step-by-step explanation:
The number of ways to arrange n things such that a things are identical , b things are identical , and so on is .
As per given , we have
Number of Geometry books = 2
Number of Algebra books = 8
Number of Pre-Calculus books =2
Total books = 2+8+2=12
Then, the number of ways to arrange them :
Hence, the total number of ways to arrange 2 Geometry books, 8 Algebra books and 2 Pre-Calculus books is 2,970.
