Answer:

532 m²

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:

$A_(\square)=a^2$

The formula of an area of a triangle:

$A_(\triangle)=(bh)/(2)$

Substitute:

$A_(\square)=18^2=324\ m^2\\\\A_{\triangle=((26)(16))/(2)=(26)(8)=208\ m^2$

The area of figure:

$A=A_(\square)+A_(\triangle)\\\\A=324\ m^2+208\ m^2=532\ m^2$
