Find the approximate area of the shaded region of the figure below.
A: 489.44 cm2
B: 181.72 cm2
C: 27.86 cm2
D: 49.07 cm2

D:49.07

Step-by-step explanation:

The area of a rectangle is LxW and the area of a semi circle is (πr^2)/2

Because you are finding the area of the pieces around the semicircle, you would subtract the area of the semicircle from the area of the rectangle:

(LxW)-(πr^2)/2

Length=14cm, Width=9cm

R is the radius of the semicircle which is half the length, r=7cm

(14x9)-((π7^2)/2= 49.07

instagram is better than go there instead lol

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
