Well in my answer i got 5.06 i rounded to the nearest hundred instead of putting all of the numbers behind the 6.
In lowest terms the answer would be 8 1/3
Formula: 1/2(d1)(d2), 12+4=16/2.3+2.3=4.6, 16*4.6=73.6, 73.6/2=36.8. Area=36.8
-Hope this helps! :)
The weight (or mass) is irrelevant.
The period t = sqrt(2*pi*sqrt(l/g) where g is the acceleration due to gravity.
so t = 2*pi*sqrt(5/9.8) = 4.49 seconds.
Frequency = 1/period = 0.223 Hertz.
