The total length is 49m^2

This is how I got the answer:

You have to set up the equation as so:

0.5 ( 3.14 * 7.5^2 - 3.14 * 5x^2 )

( * = multiply and ^ means squared )

Then after doing that it should look like this:

0.5 * 3.14 ( 56.25 - 25 )

Order of operations do what in the parentheses first

0.5 * 3.14 ( 31.25 )

When you multiply this out you get 49.087

Then you round up which gives you 49

Hope this Helps!
