Is the area of equilateral triangle E less than the area of square C ?
(1) A side of square C is \(\frac{2}{3}\) the length of a side of triangle E.
(2) The sum of the perimeters of triangle E and square C is 17
square's side 2/3of the equilateral triangles side
unique value obtained
ex - side of square = 2 side of triangle = 3
area of square = 4
area of equilateral triangle = rt3 /4 x 3 x 3 on calculation we can know the value
sufficient
(2) perimeter = 17
multiple solutions for perimeter possible
4a +3b = 17
no unique ans
(A) imo
