Answer:
142m
Step-by-step explanation:
This problem can be solved by simply using the pythagorean theorem, as you stated at the beginning of the problem, which is: 
You are given the <em>a</em> side and <em>b</em> side that are needed for this equation, so it's all a matter of plugging in the information you have:





Now, because the <em>c</em> is still squared, you must take the square root of 20200 in order to get the length of just side <em>c</em>:
≈142m
The sign isn’t switched. [ ie, -7 < 161 = 7 > -161 ]
Explanation :
When multiplying or dividing by a negative the sign flips.

Answer: You basically have to 2xlw+2wh+2lh which means
2 multiplied by the length and width + 2 x the width and the height+ 2 x the length and height
Example:
l= 2
w=5
h=4
2x2x5+2x5x4+2x2x4
I hope this helps
