You’re gonna use Pythagoras Theorem. A^2+B^2=C^2 so it’s gonna be 4^2+2^2=C^2 (we are trying to find “c”which is the hypotenuse. So 4^2 is 16 and 2^2 is 4 so 16+4=C, so C Is 20 then u get the square root of 20 which is 4.47 :)
You just have to add them together because that is perimeter.
I don’t understand that’s not a question?
Use Photomath it will probably help
2 tons is the most reasonable answer
