Answer: A = 216; B = 35
Step-by-step explanation:
Based on the information given in the question, we can then make it into a mathematical equation. This will be:
A + B = 251 ....... i
A - B = 181 ....... ii
From equation i,
A = 251 - B
Put the value of A into equation ii
A - B = 181
(251 - B) - B = 181
251 - B - B = 181
251 - 2B = 181
2B = 251 - 181
2B = 70
B = 70/2
B = 35
Since A = 251 - B
A = 251 - 35
A = 216

Answer:
B
Step-by-step explanation:
The interior of the 4 triangles in the rhombus are right angle triangles. In addition AC is bisected by BD and BD is bisected by AC. Those form the sides of the right angle triangle.
So the sides of the right angle are
- 1/2 17 = 8.5 and
- 1/2 15 = 7.5
The area of one right angle is
- 1/2 * 8.5 * 7.5 = 1/2 * 63.75 = 31.875
- But there are 4 of them
- Area of the rhombus = 4 * 31.875 = 127.5
The answer is B
