Question

the length of room is three times with breadth if the breadth is 15 M find its area and also find its flooring at the rate of 45 rupees per square metre​

Answer 1

Answer:

30375

Step-by-step explanation:

Breadth = 15m

Lenght = 3*breadth = 3*15 = 45m

Area of room = l * b

                       = 45 * 15 = 675m²

Cost of flooring 1m² = 45 rupees

Cost of flooring 675m² = 45 * 675      

                                      = 30375 rupees

Answer 2

Answer:

length = 3b

breath=15cm

length=3*15=45m

are of room = length* breadth

= 15*45 m²

=675m

if the cost of 1 m² flooring = 45 r

than the cost of 675 m =674*45r

=30375r
