The width of a cloth is 170 cm. Calculate the length of the cloth required to make 25 diapers, if each diaper requires a piece of cloth of size 50 cm by 17 cm. |

Answer» Given that length of the diaper = 50 cm Breadth of the diaper = 17 cm Area of cloth to make 1 diaper = Length x Breadth = 50 cm x 17 cm = 850 cm2 Thus, Area of 25 such diapers = (25 x 850) cm2 = 21,250 cm2 Area of total cloth = Area of 25 diapers = 21,250 cm2 It is given that width of a cloth = 170 cm Length of the cloth = Area of cloth We have width of cloth = 170 cm Length of a cloth = 21,250/170 cm = 125 cm Hence, length of the cloth will be 125 cm. |
