Answer:
12.5 un^2
Step-by-step explanation:
The formula for area of a trapezoid is (a+b)/2 *h
a and b are the shorter and longer bases respectively. H is height, you have both.
Simply plug it into the equation and find your answer.
(2.5+7.5)/2 *2.5 = 5*2.5 which is equal to 12.5. Add units.

Answer:
2160°
Step-by-step explanation:
The sum of interior angles of a convex n-gon is ...
angle sum = 180(n -2)°
When n=14, the angle sum is ...
angle sum = 180(14 -2)° = 2160°

Answer: a²+2b+2ab
Step-by-step explanation:
(2a²+62+2b+1)-(a²+62-2ab+1)
2a²+62+2b+1 - a²-62+2ab-1
a²+2b+2ab
I'm not sure it is for sure a real number or a rational number.
