To solve this you have to use the Pythagorean Theorem.
Which is a²+b²=c²
CF,CD,and DF makes a triangle
Substitute it in
a²+8²=17² Add
a²+64=289 Subtract 64 to get a alone
a²=225 Square root it
a=15
-0.04, -3/8, -0.38 is the answer
Rope = 225 cm
Needed rope = 11/2m = (11/2) × 100 cm = 550cm
So, rope needed to be cut
= 550cm - 225cm
= 225cm
=225/100m
=2.25 m
