Answer:
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 × 10
=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
