Answer:

B) 119.1

Explanation:

First, find your circle area


A=\pi r^(2) \\A=\pi 7^(2) \\A=153.9

Then get the area of the square, we will worry about the tringles on each side in the last step.

l=12

w= 14 (Radius of circle times 2)

A=wl

A=14*12

A=168

Now the triangle

h=14 (Radius of circle times 2)

b=(27 - 12) / 2 = 7.5 ( total length 27 minus 12 divided, by 2 since there's 2 triangles on each side.


A=h(b)/(2) \\A=14(7.5)/(2) \\A=52.5

Now add 2 triangles, the square and substract the circle

52.5+52.5+168 = 273

273 - 153.9 = 119.1 in^2
