Answer:
532 m²
Step-by-step explanation:
We have a square with the side a = 18m and a triangle with the base
b = 18m + 8m = 26m and height h = 16m.
The formula of an area of a square:
[tex]A_{\square}=a^2[/tex]
The formula of an area of a triangle:
[tex]A_{\triangle}=\dfrac{bh}{2}[/tex]
Substitute:
[tex]A_{\square}=18^2=324\ m^2\\\\A_{\triangle=\dfrac{(26)(16)}{2}=(26)(8)=208\ m^2[/tex]
The area of figure:
[tex]A=A_{\square}+A_{\triangle}\\\\A=324\ m^2+208\ m^2=532\ m^2[/tex]
