Will needed exactly 83 m of cloth to make 20 short identical flags and 9 long identical flags. He had some cloth which was just enough to make all the short flags and 4 long flags. He used 113
12 cm for each short flag.
- How much cloth would he need to make 1 long flag?
- How much cloth was he short of to make the remaining long flags?
(a)
Length of 20 short flags + Length of 9 long flags = 83 m
1 m = 100 cm
Length of cloth for each short flag
= 113
12 cm
= 113.5 cm
= 1.135 m
Length of cloth for 20 short flags
= 20 x 1.135
= 22.7 m
Length of cloth for 9 long flags
= 83 - 22.7
= 60.3 m
Length of cloth to make 1 long flag
= 60.3 ÷ 9
= 6.7 m
(b)
Number of remaining long flags that Will needed
= 9 - 4
= 5
Length of cloth that he was short of
= Length of 5 long flags
= 5 x 6.7
= 33.5 m
Answer(s): (a) 6.7 m; (b) 33.5 m
