Write a real world problem when you would have to multiply 120 and 75

Some students would like to build a large right angle for a large triangular banner they'd like to hang. If one of the rods is 120 feet, and they'd like to make the second one 75 times the length of the shorter one, how long would the rod need to be made by the students?

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
