Determined the perimeter and area of the following figure. Use 3.14 for pi

Step-by-step explanation:

first you will put a line in the missing part of the inside of the figure.Once you do you will see that there are two figures.

to find the diagonal of the half-circle : 7cm-2cm-1cm=4cm

Now use the area formulas for each figure.The area of the semicircle is pi×d/2.The area of the rectangle is a×b.

A of semicircle =3.14×4cm/2=6.28cm²

A of rectangle =7×3=21cm²

to find the perimeter of them:

P of semicircle = 3.14×4=12.56cm

P of rectangle =2(7+3)=14+6=20cm

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
