HI! Friends.

I have been solving these problems just by plugging in values but at times it becomes too slow, When the number is big or quite difficult to calculate, So

I want to know is there a particular formula to solve these kind of problems.

Please post if you have any suggestions to solve these kind of problems.

Sides of Isosceles triangle are a,a and asqrt(2) with hypotenuse asqrt(2)

Perimeter=a+a+asqrt(2)=2a+sqrt(2)--Eqn1

-->2a+asqrt(2)=16+16sqrt(2)

we need to find value of a to find value of hypotenuse.

Assume 2a=16 or 2a=16sqrt(2)

If 2a=16,a=8

sub a=8 in Eqn1

Perimeter=16+8sqrt(2).Not satisfied


If 2a=16sqrt(2),a=8sqrt(2)

sub a=8sqrt(2) in Eqn1

Perimeter=16sqrt(2)+16.Satisfied

Hypotenuse=asqrt(2)=8sqrt(2)*sqrt(2)=16

Hope this clarify!!!

just remember that sides dont always have to be integer...
take side as 8 root(2)
so p = 8 root(2) + 8 root(2) + root(2) 8 root(2) = 16 root(2) + 16...
