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?

I believe the answer is exponential growth(B) if I am not mistaken

Step-by-step explanation:

exponential because of the word tripled

growth because the number of cars increase

so, the answer is exponential growth
