A plot is in the form of a rectangle *ABCD* having semi-circle on *BC* as shown in Fig. 20.23. If *AB* = 60 m and *BC* = 28 m, Find the area of the plot.

Area of the plot = area of the rectangle + area of semi-circle

Radius of semi-circle =

Area of the rectagular plot = length × breadth = 60 × 28 = 1680 m^{2}

Area of the semi-circular portion =

= = 308 m^{2}

Therefore, the total area of the plot = 1680 + 308 = 1988 m^{2}
