Question

( A C=x+2 y=3 )
( B D=2 x+y=3 . .6 )
3) Solving 4 ii
We get o(1.1).
( m= )
Ar. of ( 11 mathrm{g} )
binu Doth diayonal are Equol. So it
is c squari, Rhombur or rectayle. ( = )
SIUH IT ( A C=frac{-1}{2}[because y=m times+. C] )
( f ) blope ( 7 B D= )
( f_{1} x m_{2}=+1 )
( therefore ) phothect of ( s ) lom ( eq-1 ) if isnot square or Rhombung
( therefore A D C D ) is Rectayth.
( Rightarrow quad a^{2}+b^{2}=4^{2}=16 )
( a^{2}+frac{64}{a^{2}}=16 )( quad a times b=8 )
( b=8 / a )
:) ( a^{4}+64-16 a^{2}=0 )
( Rightarrowleft(a^{2}-8right)^{2}=frac{a-1 a^{2}=8}{sqrt{a}=2 sqrt{2}} )
( operatorname{sen} sqrt{13-2 sqrt{2}} )

# Read the following passage and answer the questions that follow. Let ABCD be a parallelogram the equation of whose dia parallelogram the equation of whose diagonals are AC:X + 2y = 3; BD: 2x + y = 3.14 length of diagonal AC = 4 units and area of ABCD = 8 sq. units. The length of other diagonal BD is (B) 20 (D) 5 (C) 2 The length of side AB is equal to 5. (A) 2158 3 (B) 2458 (C) 3/58 (D) 4V58
