Hang decorative banners along the perimeter of the backyard. Write a function

how$\_$many$\_$banners$().$ The function inputs the length of each banner and the perimeter

of the area where to hang the banners. Calculate how many banners you will need, as a

minimum, so they will touch each other. The length and perimeter should be floats but

the minimum number of banners should be an integer.

Hint: the integer division operations $//$ and $\%$ work for floats just like for integers
