We have been given that Khalil has 13.5 M of lanyard. He needs to cut the lanyards into pieces that are 90 cm long. We are asked to find the number of full-length pieces of a lanyard will Khalil be able to cut.
First of all, we will convert 13.5 meter into cm.
1 meter = 100 cm
13.5 meters = 13.5*100 = 1350 cm.
Now we will divide 1350 by 90 to find number of pieces of lanyard that can be cut from 1350 cm.


Therefore, Khalil will be able to cut 15 full-length pieces of a lanyard.
