Some one cans me to find the answer about the whole shape and tell me how do you get the answer step by step i need

First let’s call the square shape A and the rectangle shape B.

To find the area of shape A you do 24 x 24 = 576cm squared

To find the area of shape B you do 40 x 24 = 960cm squared

To find the total area you just add the two areas together
576 + 960 = 1536cm squared

x-intercept(s):

(16/5,0)

y-intercept(s):

(0,−32)

(Sorry if wrong)
