Let's begin by identifying key information given to us:
This is a composite shape composed of a semi-circle & a rectangle. The area of the wall is equal to the area of the rectangle
AREA OF RECTANGLE
[tex]\begin{gathered} Area(rectangle)=length\times width \\ length(l)=12ft \\ width(w)=10ft \\ Area(rectangle)=12\times10=120 \\ Area(rectangle)=120ft^2 \end{gathered}[/tex]
AREA OF WALL = Area of Rectangle
AREA OF WALL =120
AREA OF WALL = 120 sq.ft
