Question

What is the area of this figure ​

Answer 1

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:

$A_{\square}=a^2$

The formula of an area of a triangle:

$A_{\triangle}=\dfrac{bh}{2}$

Substitute:

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

The area of figure:

$A=A_{\square}+A_{\triangle}\\\\A=324\ m^2+208\ m^2=532\ m^2$
