Answer:
7a - 2
Step-by-step explanation:
A perimeter is just the sum of all sides added together, so just put all the expressions together into a big equation.
2a - 3 + 2a + 3a + 1
Combine like terms
7a - 2
The mean sustained wind velocity has the equation:
v = 6.3 √(1013 - p)
If we are given with the mean sustained wind velocity of 64 m/s, then we can solve for the air pressure using the equation:
64 = 6.3 √(1013 - p)
64/6.3 = √(1013 - p)
10.1587² = 1013 - p
p = 910 millibars
