Question

The length of a room is three and half times it's width if the perimeter of the floor of the room is 90m find the length and width of the room

Answer 1

Answer:

Step-by-step explanation:

Let length be l and width be b

So according to condition:

L=3/2*b

Because perimeter=90m

2(l+b)=90

L+b=45

3/2b+b=45

5b/2=45

B=18m

So l=27
