Finding area ? <br><br>How did they get a=90 in sq

Burka [1]

Step-by-step explanation:

The total area in the figure can be divided into two areas.

The $area_{rectangle}$ is the area of the $8\times 10$ rectangle.

The $area_{triangle}$ is the area of the adjacent triangle to the rectangle.

$area_{rectangle}=length\times breath=10\times 8=80$

$area_{triangle}=\frac{1}{2}\times base \times height=\frac{1}{2}\times 4\times 5=10$

Total area= $area_{rectangle}+area_{triangle}=$ 90
