Can someone me find the area and perimeter

Part b:

I'm gonna divide the figure into 3 rectangles.

1st Rectangle;

Length (l) = x

Width (w) =  = 2 

Area (A) = lw = x*2 = 2x

2nd Rectangle;

l = x - 1

w = 2

A = lw = (x - 1)*2 = 2x - 2

3rd rectangle,

l = x

w = = 2 

A = lw = x*2 = 2x

Hence, total area of the figure = 2x + 2x -2 + 2x = 6x -2

Perimeter of the figure = 6 + x + 2 + 1 + 2 + 1 + 2 + x = 2x + 14

Part c:

I'm gonna divide the figure into 2, semi circle and rectangle.

Circle,

Radius (r) = 2

Area =  

Rectangle,

Length (l) = Diameter = 2 * Radius = 2* 2 = 4

Width (w) = x

Area = lw = 4*x = 4x

Hence, total area of figure = 12.56 + 4x

Perimeter = 4 + x + 0.5*circumference + x = 2x + 4 +  = 2x + 4 + 2*3.14 = 2x + 4 + 6.28 = 2x + 10.28
