Question

the length of aroom is 1.5m more than is breath.if the perimeter of a room is 63m​

Answer 1

Answer:

The length of the room= 16.5 m and breadth= 15m

Step-by-step explanation

let the breadth be 'x'

then, length= x+1.5

perimeter= 2(length + breadth)

so, 63m= 2 [ (x+1.5) + x]

63/2 = x + 1.5 + x

31.5 = 2x + 1.5

2x= 31.5- 1.5= 30

x= 30/2

x+1.5 = 16.5

Answer 2

Answer:

the length of the room=16.5m and breadth of the room=15m.

Step-by-step explanation:

Given,

The Length Of the room= 1.5m + The breadth of the room

If Length = l And Breadth= b

Therefore, l = 1.5 + b

We know,

The perimeter of the Room = 2(l + b)

                                        63 = 2(1.5 + b + b)

                                        63 = 2(1.5 + 2b)

                                        63 = 3 + 4b

                                        4b = 63 - 3

                                        4b = 60

                                          b = 60/4

                                          b = 15m

therefore, l = 1.5 + 15 = 17.5m

Thus, the length of the room is 17.5m and the breadth of the room is 15m.
