Question

Хватит ли 20м 50 см ткани, чтобы сшить шторы на 4 окна, если на каждое окно расхоуют 2 полосы ткани длинной по 2м 50см

Answer 1

1)250+250=500 (см) ткани израсходуют на одно окно
2)500*4=2000 (см) на 4 окна 
3)2050-2000=50 (см) хватит, ещё останется 50 см.

Answer 2

Calculating Fabric Needed for Curtains

To determine if 20m 50cm of fabric is enough to sew curtains for 4 windows, each requiring 2 strips of fabric measuring 2m 50cm in length, we can calculate the total fabric required.

Calculation

- Total fabric required for 1 window: - 2 strips * (2m 50cm + 2m 50cm) = 10m

- Total fabric required for 4 windows: - 4 windows * 10m = 40m

Conclusion

Based on the calculations, 20m 50cm of fabric is not enough to sew curtains for 4 windows, each requiring 2 strips of fabric measuring 2m 50cm in length. You would need at least 40m of fabric for this project.
