Are you learning about the simple square roots, as in square root of 36 for example? If so.. the best "trick" that I can think of to make it easier is if you know your multiplication pretty well, then it should be helpful.

Square root of 36 is 6 because 6 times 6 equals 36.
Square root of 49 is 7 because 7 times 7 equals 49.
Square root of 81 is 9 because 9 times 9 equals 81.
And so on.

PLEASE HELP ME RN PLEASE ​
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}

please rate well and mark BRAINLIEST.
