A) 150
B) 75
C) 75/2
D) None of these
Correct Answer: B
Solution :
[b] Here, centre is \[A(1,2)\], and tangent at \[B(1,7)\] is \[x.1+y.7-1(x+1)-2(y+7)-20=0\] ?. (1) Or \[y=7\] Tangent at \[D(4,-2)\] is \[3x-4y-20=0\] ?. (2) Solving (1) and (2), we get C is \[(16,7)\] Area \[ABCD=2(Area\,\,of\,\Delta ABC)=2\times \frac{1}{2}AB\times BC\] \[=AB\times BC=5\times 15=75\] unitsYou need to login to perform this action.
