we know that
the area of the rectangular banner is equal to

where
W is the wide of the banner
h is the height of the banner
in this problem


In the formula of the area solve for h

Substitute the values of W and A

therefore
the answer is
the height of the banner is 
Answer:
it equals 8458
Step-by-step explanation:
Caculator
<span>c) 45 degrees west of south</span>
(0,30), (1,20)
(20-30)/(1-0) = -10/1 = -10 slope
We know y intercept is 30
Equation: y = -10x + 30
(n - 2)*180
Therefore, (8 - 2)*180
Which equals to 6(180) or 1080
Hope this helps! :)
