Answer:
Step-by-step explanation:
The area can be found two different ways
<u>First, addition of two sections:</u>
- 3*4 + (7- 4)*(3 - 2) =
- 12 + 3*1 =
- 12 + 3 =
- 15 unit²
<u>Second, removal of section:</u>
- 7*3 - 2*(7 - 4) =
- 21 - 2*3 =
- 21 - 6 =
- 15 unit²
Answer:
a = 8
Step-by-step explanation:
AB / XY = CB / ZY
17 / 25.5 = a / 12
cross-multiply:
25.5a = 17(12)
25.5a = 204
a = 8
