length of the gymnasium = 50m
breadth of the gymnasium = 30m
a/c to question,
a running track 2.5m wide runs all round it on the inside .
so, area of the track = area of gymnasium - area of part of gymnasium which is inside the track
= 50m × 30m - (50 - 2 × 2.5 )m × (30 - 2 × 2.5)m
= 1500 m² - (50 - 5)m × (30 - 5)m
= 1500 m² - 45 × 25 m²
= 1500 m² - 1125 m²
= 375m²
hence, area of the track is 375 m²
breadth of the gymnasium = 30m
