Question

a room is 13m long and 9M broad find the cost of carpeting the room with a carpet 75cm broad @ 65 rupees per metre​

Answer 1

Explanation:

First find the area of the floor using formula,

A = l × b

Where l = length of the room, and b = breadth of the room

A = 13 × 9 = 117 m2

Let the length of carpet in meters be x

The total area of carpet 0.75 x

0.75x = 117

X = 156 m

cost of carpeting 65×156 = 10140

hence the total cost is Rs 10140
