Download Solution PDFGiven Data:
Length of the room: 17 m
Width of the room: 9 m
Width of the carpet: 60 cm (or 0.6 m)
Cost of the carpet per metre: 40 paisa
Concept:
The carpet cost will be determined by the total number of required carpet strips multiplied by the length of each strip and the cost per metre.
Solution:
⇒ First step is to calculate the number of carpet strips. This is given by dividing the width of the room by the width of the carpet.
⇒ Number of carpet strips = Width of room / Width of carpet = 9 / 0.6 = 15 (strips)
⇒ The cost of carpeting the room is then calculated by multiplying the number of carpet strips, length of each strip and cost per metere.
⇒ Cost = Number of carpet strips × Length of each strip × Cost per meter = 15 × 17 × 40 (paisa)
⇒ Substituting the given values, we get Cost = 15 × 17 × 40 = 10200 paisa
⇒ paisa to rupees (as 1 Rupee = 100 Paisa), we get Cost = 10200 / 100 = 102 Rupees
Therefore, the cost of carpeting the room is 102 Rupees.
