Advocard [28]

Answer:

1.

\frac{n^{2} - 1 }{2}

2.

\sqrt{29}

Step-by-step explanation:

Area of triangle=1/2×b×h

=

\frac{1}{2}  \times (n - 1)(n + 1)

\frac{( {n}^{2} + n - n - 1) }{2 }

\frac{ {n}^{2} - 1 }{2}

2. Area of triangle=14

\frac{ {n}^{2} - 1 }{2}  = 14

{n}^{2}  - 1 = 28

{n}^{2}  = 29

n =  \sqrt{29}
