Question

a room is 14 m long and 12m wide. find the cost of carpeting it at the rate of rupees 60.5 per meter.​

Answer 1

Answer:

length of the room= 14m

breadth of the room = 12m

Area of the room = length × breadth

= 14×12

= 168m²

total cost = 168 × 60.5= Rs.10164

Answer 2

Answer:

Answer

Given 

Length of the room =13 m

Breadth of the room =9 m

Area of the room = (length \times breadth)

=(13×9) m2

=117 m2

Let the length required of the carpet be x m

Breadth of the carpet =75 cm=0.75 m

Area of the carpet =(0.75×x) m2

=0.75x m2

For carpeting the room

Area converted by the carpet  = Area of the room

0.75x=117

x=117/0.75

x=156 m

Hence, length of the carpet =15 m

1 m carpet cost = rupees 65

156 m carpet cost will be =(156×65)

= Rupees 10140
