What’s the area of this figure? i need finding the area of the semicircle then the whole thing

219.25 km^2.

Step-by-step explanation:

We can split this into 2 rectangles and 1 semicircle.

The area of the longer rectangle whose longest side is , at the bottom, 21 km and width 6 km =  21 * 6 = 126 km^2.

Area of the smaller rectangle = 6 * 9 = 54 km^2.

The diameter of the semicircle =  6 + 9 - 9 + 4 = 10 km  so its radius is 5 km.

The area of the semicircle = 1/2 pi r^2

= 1/2 * 3.14 * 5^2

= 39.25 km^2.

So the area of the whole figure = 126 + 54 + 39.25

= 219.25 km^2.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

i think the answer is b
