3. draw BC perpendicular to BA
therefore angle BDCand ADC r equal to 90 degree
therefore
if angle C is equal to theta
then
BC is equal to 13 DC is equal to 12
if BC is equal to 13 then AC is also equal to 13(given)
therefore,
perimeter is equal to 56

2)
V(x) = 2( x + 3 )² + 11
Function will attain it's minimum value when
( x + 3 )² is minimum.
And minimum value of
( x + 3 ) ² is 0 At x = -3
So, minimum value of given function is 11 At x = -3
