Answer:
First one is 7.1415926,
Second one is [tex]84 inch^{2}[/tex]
Step-by-step explanation:
First for the square plus the two half circles: The two half circles are semi-circles, so two semi-circles put together equals a full circle.
Equation for the circle:
[tex]\pi (2/2)^{2} \\=\pi (1)^{2}[/tex]
=[tex]\pi[/tex]
≅3.1415926 [tex]inch^{2}[/tex] (This is too long for me to write down, actually no body can write it down , since it's an infinity unrepeating decimal)
Then the square's area is:
[tex]2^{2} \\=4[/tex]
Lastly 4+3.1415926
=7.1415926
Second one I am going to draw in the file first, then I'll write how I solved it here!
OK, so:
[tex](5)(10)+(7)(4)+(15-(5+7))(4)/2)\\=50+28+(12/2)\\=78+6\\=84 inch^{2}[/tex]
HOPED I helped!
