Step-by-step explanation:

For this parallelogram to exist least value of x should be 4.
Because if x = 3
(x - 3)= 3 - 3 =0
Thus width of parallelogram would become zero as a result area of parallelogram would become zero i. e. Parallelogram won't exist.
I think you forgot to put a picture in..
A) 68.8
b) 5.9
c) 634.9
d) 90.0
28.6
since the 0.5 is the one to be rounded and since the next number is 5, it gets rounded up.
