Question

a room is 13 m long and 9 m broad. find the cost of carpeting the room with a carpet 75 m broad at the rate of Rs. 6.40 per meter.

Answer 1

Hey,

length of room = 13m
breadth of room = 9m

then,

area of room = l * b

area = ( 13 * 9 )m

area = 117m²

and,

let the breadth of carpet = 75m

the length of carpet = area / breadth

length = 117 / 75

length = 1.56m

and then,

the cost of carpet = 1.56 * 6.40\m

cost = 9.984. @
