I got 22.85 feet as well because the perimeter of the three sides of 5 feet equal 15 feet. And then you find the circumference of the circle and then divide that by 2 like this. You multiplty 3.14 by 5 which equals 15.7 and then divide by 2 which equals 7.85 feet. After that, you add up the circumference and the perimeter.And then you get a grand total of 22.85 feet.

22.85 because their are three sidesthat are5 feet long that equals to 15 the you find the circumference anddivide it by 2 because that is a half circle the formula to find the circumference is c=pitimes diameter and the diameter is 5 (the radius as shown is 2.5) times 3.1415 is 15.7 and since that has to be divided by 2 15.7 becomes 7.85+the earlier 15 it equals 22.85

Yeah, for whatever reason, they included the side of the square even though they shouldn't have.
