Is the perimeter of triangle T greater than the perimeter of square S?
(1) The length of the longest side of T is twice the length of a side of S.
(2) T is isosceles.
Question is if sum of three sides of triangle> sum of 4 sides of square or 4S
(1) The length of the longest side of T is twice the length of a side of S.
Length of longest side = 2S (if length of side of square= S)
Length of longest side +length of other two sides
2S + >2S (Sum of two sides of triangle is always > third side)
>4S
Hence Sufficient.
(2) T is isosceles.
Not sufficient
A is the answer
