Question

Hi,please help to solve this question. Thanks.

Answer

Every 2.4 m length of the wall –> 21 ‘Suns’ and 12 ‘music notes’

                                                21 – 12 = 9

                9 more ‘suns’ than ‘music notes’ for every 2.4 m

                108 ÷ 9 = 12

                12 x 2.4 m = 28.8 m

                

Answer: 28.8 m
