Answer:
740200625 square rooted equals

21/2 is 10.5 so that would be the length of the diagonal near the 4 and the side would be 4 which 10.5 is the lengths of the other 2 diagonals so you take LxW
The answer is 168!!!!!!!!!!!!!!!!!!!
Let x = one leg. the base is then 3x-17. the perimeter I'd given by x+x+3x-17=33
5x-17=33
5x=50
x=10
2 legs are 10 each and base is 13
