The value of shortest side of quadrilateral is 11 meters.
Let the shortest side be x. So, the other three sides of quadrilateral will be (x + 1), (x + 2) and (x + 3). The perimeter of quadrilateral will be the sum of all the sides of quadrilateral. Representing the equation for same -
x + x + 1 + x + 2 + x + 3 = 50
Performing addition on Left Hand Side of the equation
4x + 6 = 50
Shifting 6 to Right Hand Side of the equation
4x = 50 - 6
Performing subtraction on Right Hand Side of the equation
4x = 44
Shifting 4 to Right Hand Side of the equation
x = 44 ÷ 4
Performing division on Right Hand Side of the equation
x = 11
Therefore, the shortest side fo quadrilateral is 11 meters.

assuming you means k = log_2(3) [as log(2)3 is the same thing as 3log(2) due to multiplication being commutative]
given log(ab) = log(a) + log(b)
log_2(48) = log_2(3) + log_2(16)
8.5X60 = 510 feet/min
510X60 = 30,600 feet/hour
