Find the missing measurement.

Answer:
Height Length: ( About ) 5.8 feet; Option B
Step-by-step explanation:
~ We are given the Area of this parallelogram ⇒ ( I presume ), so let us apply the general formula for quadrilaterals, besides particular exceptions: base * height ( altitude ) ~
The base is known the be 9.6 feet, the Area 55.7 feet^2, so let us substitute these values into the formula for a basic quadrilateral as to solve for height. At the same time let us declare x ⇒ height of the quadrilateral:
55.7 = 9.6 * x,
x = 55.7/9.6,
Height Length: ( About ) 5.8 feet
