Answer:
225 square meters
Step-by-step explanation:
Here, we want to get the area of the given shape
The area is a trapezoid and the formula for the area of a trapezoid is;
A = 1/2 (a + b)h
where a and b are the parallel sides
a = 11 m and b = 19 m
h is the height and it is = 15 m
so we have the area of the shape as;
A = 1/2(11 + 19)15
A = 1/2(30)(15)
A = 15 * 15
A = 225 square meters
Answer: first choice
<span>"r" represents the radius of the small circle.
"R" represents the radius of the larger circle.</span>
|Ω| = 6 - number of all results
A = {1, 3} → |A| = 2 - number of (a) results
P(A) = 2/6 = 1/3
