Find the length of a track that is a rectangle and two semi circles. Rectangle is 87m long and 65 m wide

Step-by-step explanation:

larger radius R=87/2

smaller radius r=65/2

larger semi circle=1/2*2*π*R=π*R=π*87/2=87 π/2≈136.6 m

smaller semicircle = π*r=π*65/2=65 π/2≈102.1 m

length of track=87+65+136.6+102.1≈390.7 m
