The area of the composite figure is equal to the area of three rectangles
The area of rectangle is equal to
[tex]A=bh[/tex]
where
b is the base of rectangle
h is the height of rectangle
so
[tex]A=(18)(15-9)+(5+1)(5)+(1)(4)[/tex]
[tex]A=(18)(6)+(6)(5)+(1)(4)[/tex]
[tex]A=108+30+4[/tex]
[tex]A=142\ ft^2[/tex]
