120/360×22/7×21×21cm^2
this is area of 1/3 rd circle with radius 21 cm
as there are only multiplication and division signs so to have better understanding we will place bracket before where ever sign changes
(120/360)×(22/7)×21×21cm^2
cancelling 120
=(1/3)×(22/7)×21×21
= (22/21)×21×21
now cancelling 21
= 22 × 21
= 462 cm^2
