Question

Find the cost of carpeting a room 13 m long and 9 m broad with a carpet 75 cm wide at the rate of rs. 12.40 per metre

Answer 1

Hey

Given that :-
Length = 13 m
breadth = 9 m
Area = ( l * b )
= ( 13 * 9 ) m² .


Breadth of carpet = 75 cm = 0.75 m .
So , length = area / breadth
l = 13 * 9 / 0.75
l = 13 * 9 * 100 / 75
l = 13 * 9 * 4 / 3
l = 13 * 3 * 4
l = 156 m

Now ,
cost of 1 m = Rs ( 12.40 )
cost of 156 m = Rs ( 156 * 12.40 )
= Rs 1934.4
