since its 2 half circles calculate are for a circle would be area = piR^2

the diameter is 100 feet so radius would be 100/2 = 50 feet

using 3.14 for pi you get 50^2 x 3.14 = 7850 square feet for the circle area

rectangle area = l x w = 100 x 212 = 21200

now add them

21200 + 7850 = 29050 square feet

5 can go into 10 and 20 so you just want to divide them by five which gives you
2/4.

its still not simplified yet so 2 can go in to 2 and 4 so we divide them your answer should be 1/2

so your simplified answer for 10/20 is 1/2

so 10/20=1/2

same thing for 30/60

10 can go into 30 and 60 so we divide them by 10

you should get 3/6

its still not simplified

3 can go into 3/6 so we divide them by 3

you should get 1/2

so 30/60= 1/2

10/20 = 1/2.

30/60 = 1/2

so your simplified answer for both of them is 1/2

I hope this helped!
