Answer:

Step-by-step explanation:
If by this you mean perpendicular bisectors, then they would intersect at one point.
Answer:
60 u²
Step-by-step explanation:
<u>Finding</u><u> </u><u>second</u><u> </u><u>diagonal </u><u>:</u><u>-</u><u> </u>
- d' = √{ 17² - 8²}
- d' = √{ 289 - 64 }
- d' = √{ 225 }
- d' = 15 u
<u>Using</u><u> </u><u>formula</u><u> </u><u>:</u><u>-</u><u> </u>
- A = 1/2 * d * d'
- A = 1/2 * 15 * 8
- A = 15 * 4 u²
- A = 60 u²
