Does anyone know the steps to this you don't have to give me the answers but just the steps plz

a. For the outside perimeter, as you can see, it consists of half-circle at the top and a rectangular below,

Perimeter = Perimeter of half circle + Perimeter of rectangular

                = 2 x pi x 10/2 + (60 + 20) x 2 = 10pi + 160 = 191.42

b. Area of triangle 3 = base x height x 1/2 = 20 x 16/2 x 1/2 = 80

c. Area of rectangular 1 = length x width = (20/2) x width = 10 x width (here width is undefined).

d. Area of triangle 5 = base x height x 1.2 = 16 x 20/2 x 1/2 = 80

e. Area of half-circle 10 = Radius^2 x pi x 1/2 = 10^2 x pi x 1/2 = 50pi = 157.08

a, b, c, d, e are marked from top to bottom of table you need to fill in.

Hope this helps!
