Question

120/360×22/7×21×21cm^2 cancel with full explain​

Answer 1

22×21cm^2

462cm^2

therefore answer is 462

Answer 2

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
