R=√(8²+6²)
=√(64+36)
=√100
=10cm
=√(64+36)
=√100
=10cm

since ant moves 6cm at right angle after travelling a distance of 8 cm, we take it as she moved by making a triangle pqr right angled at q.
then in order to get the shortest distance (green line) we use Pythagoras theorem
thus, pq^2+qr^2=pr^2
√64+36 = pr
√100=pr=10cm.
steps are taken out!...hope u won't mind.
like the answer, mark it!...
