Question

• The cost of papering four walls of a room
at 14 per square metre is * 3,150. The
height of the room is 5 metres. Find the
length and the breadth of the room, if they
are in the ration 4 : 1.​

Answer 1

Answer:

L=18m

and

b=4.5m

Step-by-step explanation:

area=3150/14=225 sq.m.

=h*(l+b+l+b)

=2*h*(l+b)=2*5*(l+b)

so L+b=22.5m

=4b+b=5b

so B=4.5m

and L=18m
