Step-by-step explanation:
area of hall= 22/7 * 120* 120
area of carpet= 22/7* 106*106
area of uncovered part= area of hall- area of carpet
= 22/7 * 120*120 -22/7 *106*106
=22/7((120*120)-(106*106))
=22/7(14400-11236)
= 22/7(3164)
= 22*452
= 9944cm^2

Answer:
Step-by-step explanation:
Area of circle = πr²
Area of circular hall = π×120²
Area of circular carpet = π×106²
Area of hall uncovered by carpet = area of circular hall - area of carpet
22/7×120×120 - 22/7×106×106
= 9958.20cm²
