Answer :
so we know that the diagonals of a rectangle are equal than
3c/9 = 4 - c
c/3 = 4-c
c = 3(4-c)
c = 12 -3c
4c = 12
c = 12/4
c = 3
so in this case the length of AC = 3*3/9 = 9/9 = 1 and the length of
BD = 4 - 3 = 1
hope this will help you
3c/9 = 4 - c
c/3 = 4-c
c = 3(4-c)
c = 12 -3c
4c = 12
c = 12/4
c = 3
so in this case the length of AC = 3*3/9 = 9/9 = 1 and the length of
BD = 4 - 3 = 1
hope this will help you
