The length of a triangle are 4cm and 7cm what is the measure of the third side

1 answer

No way to tell, unless the triangle is a right triangle, in which case the third side is either

√(7^2-4^2) = √33
or
√(7^2+4^2) = √65

All we really can say is that if the third side has length x, then

7-4 < x < 7+4
3 < x < 11
