Can someone help pls!!

C) 42.14 cm²

Step-by-step explanation:

Recall the area formulas for a square and circle:

Area of square: A=s²

Area of circle: A=πr²

Given:

π=3.14

s=14

r=s/2=14/2=7

Therefore, the area of the square is A=14²=196 cm²

The area of the two semicircles is A=3.14(7)²=3.14(49)=153.86 cm²

Find the difference between the two areas to get the shaded area:

196 - 153.86 = 42.14

Therefore, the shaded area is 42.14 cm², making C the correct choice.

C

Step-by-step explanation:

1) find the area of the square

A = side^2 = 14^2 = 196 cm^2

2) find the radius of the two semicircles

radius = side / 2 = 14 : 2 = 7 cm

3) find the areas of the two semicircles

A = radius^2 x 3,14 x 2 = 7^2 x 3,14 = 153.86 cm^2

4) find the area of the shaded region

196 - 153.86 = 42.14 cm^2

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
