Question

if we know that two sides of an isosceles triangle are 3cm and 4cm and that's its perimeter is not 10cm then what is the perimeter?

Answer 1

3+3+4=10 but we’re told it isn’t 10 so it must be 4+4+3=11cm because 2 lengths in an isosceles are the same, that missing length must be 4cm to make the perimeter 11cm instead of 10
