The figure the Floor Plan of a balcony ,it consists of △ABC and semi-circle ,
(a) find the perimeter of the balcony
(b) the area of the balcony

please help me

Step-by-step explanation:

(a) In right triangle ABC,

Perimeter of Balcony = 12 + 5 + 20.41 = 37.41 m

(b) Area of balcony

okay wait before i answer, is this for your points on a graph?

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
