You see the outlined rectangle? first find the perimeter to that.
you should get 20 feet.
now the hard part, the half circle. The dotted line on the top of it how’s the diameter of the circle, the diameter is 7 feet in this case.
now you must solve this equation to get the circumference: diameter • pi = circumference
Once you get your answer ( 21.98 ) then you divide by 2 ( because it’s half of a circle ).
Now you add 20 and the circumference of your half circle ( 10.99 ).
Your answer should be 30.99! :)
