QUESTION 13 !
No, because the pythagorean relationship didnt work .
4800 cm squared + 4800 cm squared = 9800 cm squared.
4800+4800= 9800, that's not the right answer , it equals to 9,600 , that's why the pythagorean didn't work.
sorry if I got the answer wrong, just tell me in the comment box if I made a mistake , dont forget to COMMENT .
