Draw ABCD as a rectangle.
AC be the diagonal of 25 cm.
length-4x
breadth-3x
now use Pythagoras's theoram.
AC square=ABsquare +BCsquare
you will get
5. Now Length=5×4=20
breadth=5×3=15 Now you got all the necessary measurement So perimeter of Rectangle ABCD=2(l+b)=2(20+15) =2×35=70 cm.Is the answer true if not comment please
