Answer:

h = 0.64 ft

Step-by-step explanation:

$s = \frac{14 + 12 + 6}{2} = \frac{32}{2} = 16 \: ft \\ \\ A = \sqrt{(s - 14)(s - 12)(s - 6)} \\ \\ A = \sqrt{(16 - 14)(16 - 12)(16 - 6)} \\ \\ A = \sqrt{(2)(4)(10)} \\ \\ A = \sqrt{80} \\ \\ A = 8.94427191\\ \\ A \approx 8.94 \: {ft}^{2}$

A = 14h

8.94427191 = 14h

h = 8.94/14

h = 0.638571429

h = 0.64 ft
