Question

Find the cost of carpenting a room 13m by 9m with a 75cm wide carpet at the rate
of Rs 7.40 per metre

Answer 1

Answer:

Rs 1154.40

Step-by-step explanation:

Find the number carpets needed:

Given 1 carpet is 75 cm wide

Number of carpets needed = 9m ÷ 75 cm

Number of carpets needed = 900 ÷ 75 = 12

Find the total length of carpet needed:

Length of the room = 13 m

Length of carpets needed = 13 x 12 = 156 m

Find the cost:

1 m = Rs 7.40

156 m = 7.4 x 156 = Rs 1154.40

Answer: It costs Rs 1154.40
