Question

a room is 13m long 9m broad. find the cost of the carpeting the room with a carpet 75cm broad at $.50 per metre

Answer 1

l= 13 m

b = 9 m

area = l × b

= 13 × 9 = 117 m ^2

let length of carpet be x.

breadth = 75 cm = 0.75 m.

area of room = x × 0.75

117 = x × 0.75

x = 117 ÷ 0.75 = 156 m.

cost of 1 m = 50 ₹

cost of 156 m = 156 × 50 = 7800 ₹.
