The field inside a running track is made up of a rectangle 84.39 m long and 73 m wide, together with a half circle at each end. the running lanes are 9.76 m wide all the way around. what is the area of the running track that goes around the field? explain or show your reasoning.

Area of the strip = 2455.03 sq. meters

Step-by-step explanation:

We can split the total area as the sum of a rectangle and a circle.

The field inside a running track is made up of a rectangle 84.39 m long and 73 m wide, together with a half circle at each end. The running lanes are 9.76 m wide all the way around.

Total area = Area of rectangular strip + Area of circular strip

Area of rectangle =2( length width )

                              =2 (84.39 9.76)

                               = 1647.3 sq meters.

Area of circle =

                       =

                       = 807.73 sq. meters

Hence the area of the strip = 807.73 + 1647.3 = 2455.03 sq meters
