SOMEONE PLEASE HELP PLSSS WILL MARK BRAINLIEST

we know that

Area of the shaded reigion=Area of the rectangle-Area semicircle

step 1

find the area of the rectangle

A=L*W

L=8 cm

W> is the radius of the semicircle

W=8/2> W=4 cm

A=8*4> A=32 cm²

step 2

find the area of the semicircle

A=pi*r²/2

r=4 cm

A=(3.14)*4²/2> A=25.12 cm²

step 3

Area of the shaded reigion=32-25.12> 6.88 cm²

the answer is

6.88 cm²
