Answer 1

The area of a square porion(red shaded) is,

`A_1=21*12=252ft^2`

Area of the black shaded portion,

`\begin{gathered} A_2=(16-12)*(21-16.5) \\ =18ft^2 \end{gathered}`

Since 21-16.5=4.5 ft, the areaof the green shaded portion is,

`\begin{gathered} A_3=13.5*(19.5-4.5) \\ =202.5ft^2 \end{gathered}`
