m^2=(2b^2+2c^2-a^2)/4 where m is the median of triangle ABC.
one cm is 1/100th of a meter. if you have a length in cm then multiply it by 10^-2 to get the length in m. if you have the length in meters then multiply it by 10^2 to get the length in cm
It is: (x-a)^2 +(y-b)^2 = m squared
Perimeter = 2(L + W) = 2*(5.5 + 12) m = 2*17.5m = 35 m.
The kind of triangle with two sides the same length is an isosceles triangle.
