sir once check the answers only 17 should be the answer
given isosceles triangle one side has length 3 inches and another side has length 7 inches
if the third side is 3 then 3+3<7 here property of triangle is not satisfied
third side must be 7 only so perimeter =7+7+3=17
option E is correct

The third side is 7-3=4 or 7+3=10
Since the third side is greater than the shortest side then the third side can either be 7 then we have 7,7,3 triangle or 3,3,7 triangle since it's an isosceles triangle.
Hence CE
