For us to get this area, we need to draw the diagram and analyze the shapes that are within the diagram.
In this case, the diagram consists of a rectangle of 150m by 21m and two semicircles of diameter 54m.
Area of rectangle =21×150=3150m2
Area of semicircles=3.142 × 27 ×27=2290.52m2
Total area =2290.52+3150=5440.52m2
