Answer 10

Hey Ing, i thnik u had typed the first question wrong so i will use second question for explanation

Answer 11

if u draw rectangle ABCD, you will find that its diagonals are AC AND BD
In a rectangle the diagonals are ALWAYS EQUAL, so AC=BD
this means

3y
---- = 3y-4
5

3y = 5(3y-4)
3y = 15y -20
or
15y-20=3y
15y-3y=20
12y=20
y=20/12
y=5/3

Answer 12

now putting y=5/3 in ac and bd, we get

3 x 5/3 15/3 5
ac = --------- = -------- = ------ = 1
5 5 5
5 15
bd = 3y-4 = 3 x ---- - 4 = ------ - 4 = 5-4 = 1
3 3
