Answer:
423.5 sq.m
Step-by-step explanation:
Let r be the radius of circular pool.
Area of circular pool = 962.5 Sq. m.
πr² = 962.5 => r² = 306.25
r = 17.5 m.
Width of field = 3.5 m.
Total area of circular field including pool = π (17.5 + 3.5)²
= π (21)² = 1386 sq. m
Area of path = 1386 - 962.5 = 423.5 sq.m
