Answer:


Step-by-step explanation:

The track is in shape of two circles with same centre

The distance around the track along its outer edge will be

Diameter of inner circle + 2× width of track

= 70m + 2 × 10m

= 90m


Area of track = Area of outer circle -

Area of inner circle

= 22/7 ×R square - 22/7 × r square

= 6364 - 3850

= 2514 m square
