Given data:
The cost of the material per square-foot is c=$2.20.
The expression for area of the given figure is,
[tex]\begin{gathered} A=(21.7\text{ ft)(12 ft)+(}12\text{ ft)(8.5 ft)+}(20\text{ ft)(12 ft)+2(}\frac{1}{2})(20\text{ ft)(8.5 ft)} \\ =260.4ft^2+102ft^2+240ft^2+170ft^2 \\ =772.4ft^2 \end{gathered}[/tex]
The total cost is,
[tex]\begin{gathered} C=A\times c \\ =(772.4)(2.20) \\ =1699.28 \end{gathered}[/tex]
Thus, the total cost is $1699.28.
