Answer:

base = 8
(1)/(2)ft

Explanation:

The general formula for the area of a parallelogram is:

A = bh, where b = the length of the base and h = the height

Using the given values for area and height, we can solve for the missing variable of 'b':

23
(4)/(5)=(119)/(5)

2
(4)/(5)=(14)/(5)


(119)/(5)=(14)/(5)h

Multiply both sides by the reciprocal:


((5)/(14))((119)/(5))=((14)/(5))((5)/(14))h


(119)/(14)=h


h=8(1)/(2)ft
