Answer:
AB = CD = 3√5
Step-by-step explanation:
We use Pythagoras' Theorem.
AB² = CD² = 3²+6² = 9+36 = 9·(1+4) = 9·5
=> AB = CD = √(9·5) => AB = CD = 3√5
Answer:
15
Step-by-step explanation:
Okay, so we know that Base*Length=Area, so we just have to divide the area by the base, so the formula here is Area/Base=Length.
That would get us 120/8=Length,
and if we just divide 120 by 8 we get 15, so the length is 15
