    I don't think so, I guess It'll be just each block = 1unit... not necessary cm, nor m, nor none of those. since a unit isn't specific I think its appropriate

    A.Y_swagger; based on the figure you pretty much know the length of CB and AB. once you know that just use the Pythagorean theorem. A^2+B^2=c^2 once you know C^2 get the sqrt and then just add up A B C

    with that you now know two sides of the right triangle. You still need to find out the hypotneus idk how to spell it,

    a^2+b^2=c^2 where c= √(a^2+b^2) = √(5^2+3^2)=√25+9) = √(34) so to find the perimeter you add up all of them. 5+3+√(34) which as Tinman found=13.83 and yea, just having internet problems now and then
