Answer: b = 14/3 = 4.667 feet
The decimal value is approximate. In reality the 6's go on forever. Round that however you need to.
================================================
Work Shown:
b = unknown base
h = height = 6 ft
A = area = 14 sq ft
A = b*h/2
14 = b*6/2
14 = b*3
14 = 3b
3b = 14
b = 14/3
This approximates to 14/3 = 4.667 ft
