Answer:

C) 123 cm^2

Step-by-step explanation:

well if we find CD we can cut striat down C and do area of a triangle plus the area of the rectangle.

to find CD you need length of BC

BC^2 = AC^2-AB^2 --> BC^2 = 400-100 --> BC^2 = 300

BC = 300^2 --> about 17 causeing CD being 4

now we have info

triangle area is BxHx 1/2 --> 17x10x1/2 --> 85cm^2

Now we do the small rectangle area is BxH --> 4x10 --> 40cm^2

85 + 40 = 125cm^2

the only one close is 123cm^2
